 Yeah, we are here to talk to you about a lot of fun handcuff trickery today. I am Deviant from Tool. Along with me also from Tool is Dave Pochet, Dr. Tran, the dashing secret agent. And as a special benefit, we also have Ray, one of our German friends from the sport-picking groups overseas. He came all the way from Germany. Let's give him a hand, guys. We have a lot of good things that we're going to show you, but especially let's get right to our featured speaker first. Okay, hi. I was asked to talk about a few things we did in Europe with handcuffs because there's somewhat different there. One of the most, I think, funny things actually happened last year at Haar. Because the Dutch police, which is the country where the Haar takes place, has a very special kind of handcuffs. This is completely different from all the cuffs you will find in the U.S. and it has a special key. So it's shaped differently than all the keys you know. And they're very proud of that. And so they're carrying these around all the time and they were running around on the campground where all these hackers were. And one thing about the key is that they won't sell the handcuff to anybody. And as I collect sort of handcuffs, I don't really like that because they won't sell it to me. Ah, we can't sell it. The key is so secret. But they're hanging it on their belt. The top secret key. And it hasn't changed for years, what I can say. So it's the same key, but it's just still considered secret until Haar. So what we did is we used a 3D printer to replicate it. Taking the measurement from a key we got somewhere. Printing it on our 3D printer and coming with a 3D printed key to Haar. So as you saw in the previous slide, we approached the police guys there and they, oh, we printed your secret handcuff key. Can we try it on your cuffs? Of course they were going, no, no, no. This is a secret key. You don't have it. Oh, we have it. Just try it out. No, no, no. Take it. This would go to your van and try it there. Don't tell us. Oh my God. Oh my God. Everybody. Does anybody have handcuffs? Oh, so see, as you were saying, even the ninjas are afraid of the Dutch handcuffs. Okay, but the policemen were just afraid of our keys so they're running away. No, we don't take it. We won't try it. We said, you can have one try it alone. Don't tell us. We just wanted to let you know that we did set it because your key is now public. But they didn't want to. Fortunately, later on, the older one wasn't there. The younger ones didn't know. And we actually were able to try it. And surprisingly, it really worked. So for all of those who ever are going to travel to a hacker camp in Holland or something, just download your copy of the key at key.new with the dot after the e. So you can get an STL model there. You can get all the measurements from it and you can print it on these 3D printers which are getting more and more popular. Yeah, so that's the thing about these Dutch keys. If you search on the internet for 3D printer handcuffs, you will find quite some coverage, some of them funny, some of them crazy. Go search for it. So another thing I'm currently working on because this Dutch key is almost a year old, but this is not completely finished. Watch on key.new for the final. We found out that there's actually an airline restraint kit featuring another very unusual cuff because it's using an English cuff. It's called the CHUP Detainer cuff by the CHUP company. Lockpickers will know the CHUP company for high security locks like in safes and everything. The handcuff isn't that high security but still very, very hard to pick. You have to have real lockpicking skills, three-level manipulation and everything. But it's a very solid keyway. So I'm pretty sure we'll have a working model for that airline restraint kit in plastic. So you can go to the metal detector visit with any problems. So watch out on the earth for these to appear. Okay, another thing about the Dutch cuffs, if you happen to be there and don't have the key with you, we have a short video for you to see what else you can do with them if you have high tech tools like, for example, paper with you. So the paper basically blocks the mechanism and the cuff slides open. I have to warn you so that this won't work if it's correctly operated and double locked on both hands. So probably try to run away before both sides are double locked. That's an interesting fact, though, when people see that video, they usually say, oh, aren't those those big, heavily engineered handcuffs? How can you slip out of something with as simple as paper? Well, a lot of cuffs, actually, big, heavy-duty cuffs, their security isn't in. They're anti-pick resistance or manipulation resistance like these German cuffs by the Kliusso company. They're really just designed to kind of almost be like leg irons and hand irons. They're not really designed to be unpickable cuffs. Many of you have seen these cuffs as well, by the way. How many people have ever watched Firefly or Seen Serenity? When River goes fucking nuts from the Odie Bar commercial, these are the cuffs they lock her up with on the ship, man. So you've all seen Kliusso model 13s before. What you've probably never seen, though, is that same kind of a trick, that same sort of a shimming trick. You can do that on these. Again, similar cuff, big, heavy cuff. But if you have something like a sticker, do I have a sticker sitting up here? I do. Can you still hear me? So if you have, let's say, like a sticker paper backing. Because that works well, dollar bills work well. Sometimes that paper is just thin enough to slip in underneath the teeth here, but thick enough to still trip the levers. So if I can slip it under, or I just shred the paper. Yeah, let me just flip it around one last time. Demo fail. If you have dollar bills, you don't mind shredding up. You can usually do it with that too. I don't know if you can see it. It works really well with European currency, since they tend to be more plastic. Yeah, European currency, Australian currency, especially have you ever tried to rip Australian currency in half? You actually can't do it. Yeah, it's like Tyvek. But a lot of those big cuffs, you know, they're also pickable. Someone will see the actual keys that come with them. They look real serious. Here's one of our locksmith buddies just popping open those same heavy duty cuffs and he's actually picking them at a tool meeting with something that's smaller than a regular handcuff key. So just because a cuff looks really big and angry or just because the key it comes with looks really huge, it doesn't mean that it's in any way really that pick resistant. Well, let's talk more about just typical cuffs, because we're throwing all these weird foreign cuffs at these people and they may have never seen the inside of just regular cuffs before. Would you like to go over that? Absolutely. So here we have a cutaway of a simple handcuff design. This is the type that will be employed by United States law enforcement and very, very straightforward. There are not a lot of complex moving parts and again as we'll talk further on, a handcuff is not designed to be a high security restraint. It's just designed to keep someone situated while particularly during transport. That was nice. Not many moving parts. You see you've got the ratcheting arm there in group and you've got the pawl at the bottom. Both of those have ridges that interlock with each other and that just keeps it from moving in and out when you have the cuff in moving outwards, I should say. And then there's a spring that holds the pawl up so that engages the ratcheting arm. There's also the double lock bar and when that is engaged, you're not able to tighten the cuff or unlock it with the key unless you flip the key around the other way. One of the main purposes for this is to protect law enforcement from lawsuits and claims of abuse because if you ever catch someone who doesn't double lock their cuff, if someone is a little crafty, what they might do is really slam that down, crunch it up and get black and blues all over their arm and say, listen, I was being abused by this cop. So that's the main purpose for that and you'll see that very rarely where law enforcement officers not double lock a cuff. And that's really it. It's just very straightforward. Not many moving parts again and not a complicated mechanism. We've got a couple of videos here we're going to show you. Yeah, it's not a lot going on in there. Yeah, the mechanism itself is a real simple to understand thing. As you can visualize this, there's not much going on in the cuff. The parts that move don't move very far and even getting the pall to trigger down. You're just talking about fractions of an inch worth of movement. So obviously there's a lot of ways you can reach in there without the proper key and still trigger this sort of movement. And hopefully if we don't look too dumb up here we're going to show you some of those ways. For example, like a shimming attack. Shimming is the use of really thin metal inserted somewhere into a lock mechanism. You can insert thin bits of metal in one side or another on the outer edge of the cuff body and still try to get at that pall. Now the side you just saw someone pushing on, that's hard to do unless you over tighten yourself. This side over here, it's easier to slip a shim underneath because the teeth are going the right way. But of course really tight cuffs you're not always going to just get into that side. But almost, I'd say almost every cuff we have on this table, probably with the exception of some Korean ones, could be shimmed like that. And really quickly just in case you didn't understand it, that double lock mechanism, that bar underneath here. Normally it's out of the way, the key or a shim or a pick or any number of other things would allow the ratcheting pall arm to move. But if that bar clunks over, now nothing can move. The pall can't move, you can't shim it, you can't even use a key properly. The only way to get in as Dave pointed out is to bring a key around the other side. And if you see with our hands out of the way of this next shot coming around the other way, click, we'll pop that double lock bar out. Of course there are other ways of popping the double lock bar out and we're going to come back to that in a second. First though, just so they know we're not completely telling tales out of school here. So we try some shimming and picking attacks and the like. You guys want to see this? See this breakout of handcuffs? First we'll try to use some handcuff shims. Now there are real proper shims like from Searpik and those guys. Or you can just use tension tools and things like that and try to shim out. Do you want to do the video? No, we'll just do it on camera here. So who's up first? There you go. The dashing secret agent. He'll be hurt. So for these handcuffs I'm going down the side that has a split. So I have a tension tool here just from a lockpick set. I'm wedging it underneath the paw, if you can see, and I'm just pressing down. Power cops. I have some little more expensive cash here from the investment company using a very, very sin standard tensioning tool. And I go the side with the ratchet. So one thing you have to do when doing that is push in the ratchet a little with the tool. So I'm pushing the bow in a little when putting in the shim. Then it gets between the ratchet and it's open. Nice, very nice. I'm just going for the same thing Robert just did to reiterate and so you know there aren't any trick cuffs. These you just go in from the back here. Push in down. This is a standard tension wrench. You can use any bent piece of metal really. And then I'm just going to push down and it's open. So how about picking because we can pick out of these cuffs too, right? Yeah. Shall we show them some picking attacks as well? You guys want to see some picking attacks? Yeah. Go ahead doctor, what do you got there? Just a regular pair of valors. One way of telling which direction you need to pick is looking for the fulcrum where the paw is going to be pivoting on. So you can actually see the rivet here right on the handcuffs. So you know this paw is going to be flexing this way. So what you want to do is use your pick tool to just reach in there and just try to press down on the paw. Don't do this with really nice picks. Picks you just bought let's say because sometimes it will trash the pickup pretty good. We'll often see us that we'll grab some of those kinds of things. How many people have ever hated lock picking in the movies like when someone doesn't have a tensioner they're like, the door fell open and it's all fake. Cuffs actually sometimes in the movies it is kind of like that. It's just a little shitty piece of metal. A little thin piece of metal in the right place. You're just trying to catch a simple paw lever. Notice how big the bit is on the end of a typical handcuff key. It doesn't have a lot of huge reach you're just trying to reach just barely barely barely inside the key way and you should be able to trip that lever. Another really common tool you can use a lot of common things like bobby pins, paper clips and other stuff to pick a, you know, pick handcuff locks even the standard ones or some higher end ones. But I don't know if you guys have ever seen the binder clips you can get it staples where you can pinch the two pieces and then you flip it around and you clip on paper. Well there's one piece that you can use and you can pinch it and release that little silver piece bend it open and it makes an awesome handcuff key. So some people may or may not clip those on their belts every day as they go out. But I mean in all actuality though if you're in a nonviolent protest and for no reason you get scooped up and someone's not looking it might be a handy way to get out or like shine there at some place. Of course absolutely. Or if you're unlawfully restrained you can use handcuffs too. Here's a binder clip right there. Yes indeed binder clip that will work very well. So wow how we doing on time we got to keep moving along a little bit. Shall we try, you know what ask us in the Q&A room if you want to see popping out of double locks or ask us up in the lock pick village we can actually pick out of the double lock but you're going to learn even more other double lock techniques in a minute possibly here. My favorite video escape by the way I just love to throw this in any time I'm doing a handcuff talk so many people know Render Man. Render Man is a really really skinny really flexible fellow and he is able to do this sometimes at parties sometimes at you know Fed conferences and the like. It's funny that I mentioned Fed conferences because here as Jackalope cuffs him up. I've been told by my FBI buddies this video actually gets shown at Quantico now during trainings actual Render Man here. Just you know it's like alright so I'm going to get cuffed up here you know you got me done up pretty well behind the back all in place. It's like okay here I am nothing out my sleeves nothing in my pockets no special trickery just a little bit of light diet push him up my wrist a little and go zip zip zip zip blam and of course that trademark fedora of his always has his tools and everything and his picks up inside the brim I think he keeps a flash drive with a back track install up there so yeah way to go Render Man so how are we on time we're not bad on time. That double lock though when we keep talking about how the double lock should be a secondary mechanism that's kind of hard to attack and mess around with there are some physics involved however that can be exploited Tran you want to talk some more about that. So as mentioned before the double locking bar is a metal bar that when you use the little the little post on the end of a handcuff key to push that bar across that bar will prevent the paw from moving up and down you can either pick that open or you can use a little bit of physics does everyone know who that is? Exactly the apple Isaac Newton there's something called the whack attack because that bar is made of metal and has mass everyone knows objects in motion want to stay in motion so what you can do is actually whack the handcuff and cause and the momentum or the inertia of that double locking bar will want to continue moving so if you whack it in the right direction you can just pop it back into the reset position and I'll try to demo that real quick Yeah Who saw my very first DEFCON talk ever at DEFCON 13 was it? Agent X did this on stage anybody see that? Yes, wow some old timers here So here's a pair of handcuffs that are not double locked because you can tighten it what you do is use the end of a handcuff key there's a little post on the end just click it in this one's broken use the other side these are yours my are fucked up dude when you bang them too many times it's like bumping a lock eventually it's just dead I'll just use these pink handcuffs that was what you really wanted all along wasn't it yes they are I made these myself so using the post at the end of the key I just engaged the double lock the handcuff is not going to tighten at all all you have to do is smack it against something really hard like a padlock or an anvil or a rock you know with the anvil you keep in your pocket all the time and now you can over tighten it very very nice one set the double lock just by smashing down really hard physics it works bitches now there are other handcuffs I try to they have countermeasures for this one way of doing that is to have a plastic piece the plastic piece doesn't have enough mass for you when you whack it it doesn't have the same inertia so it's not going to move so that's one way of doing it using plastic and then there's another technique with the other handcuffs that you realize there's almost no mass in that double locking bar in fact the double locking bar and the spring is the same piece of metal so there's almost no mass right there and it's extremely difficult I don't think we've ever been able to use the whack attack to un-set the double lock no we never have we're going to come back to Jules a little later they really are probably our favorite cuff ever yeah who has seen these handcuffs before what a medical lock is a medical lock is actually a very high security lock I think one of the best brands here in the U.S and they actually put one of those on a handcuff so for picking you're a bit out of luck with those but as a company you should be a little careful on what cuff you put your high security medical lock on because what they use here is a standard PLS handcuff so we have this high end locking cylinder on it so here we have again a double not double locked cuff you actually need a special tool to double lock it because they put this clumsy lock on it so I'm applying the double lock just the normal way so now it's locked and I've slammed it before oops I don't have a used mine yeah he doesn't want to break my cuff you can break his own though because that housing is just high impact plastic but it is just plastic you can crack it off actually the ones you have is that a metal housing on the Desmo one this is designed with a Desmo lock this is a European lock and it's used on many of the slot machines so you can tell it's I would say even more secure than the medico so let's try it with this one here oops that's a demo effect I guess yeah okay so it took it took us three efforts okay but you see we opened the double lock without using this high security lock at all and now we can shim it so this $200 cuff is basically the same security as any other one so there was also another thing you were going to tell us about cuffs you brought with us right and regarding that double lock trickery with the German cuff yeah that's another double lock fail you'll see in Germany we have usually basic normal cuff with a slightly different key but it's the principle is basically the same this one here has been used in the past I think until 2005 or something and they're still around so they stopped making them now but they're still around and for 20 years or something those were around and the nice thing about this is that they are the only cuff that I know of that's in police use which you can escape from without any tool at all I won't show it on hand because the demo is so effective in the last but let's see so what I'm doing what I'm doing is you remember the pictures from before here's the double lock you can activate it with the fingers it's actually clever designs as a police officer doesn't have to use the top of his handcuff key you can just activate the double lock like this but what I do is by pushing in the bow a little like almost a complete click but not really so it moves down the red shirts as far as possible and then put in the double lock push in push it in even more so the double lock goes against the red shirts and holds them down and the cuffs open so this of course again is possible if the double lock hasn't been engaged before but the slamming or ramming just works nice on these so slam them open and use the double lock and escape without any tool at all very nice oh but now they have new ones but don't be too afraid so those new ones they'll skip them this is a very difficult design they have a three-bitted key and they're very expensive and everything in sort this will be the ultimate handcuff ever but they had a nice design floor again the three-bitted key is used on the paws but it's not used on the double lock and no shim protection so actually you can open them like the other ones so if you go to Germany and are some bad guys have the cops cuffs because German police of course never would cuff you unlawfully so don't be afraid too much to go to Germany as a German without a tool, obviously normal tools do you want to show the one last three-bitted fail on the Kyung Changs as well the next one oh yeah and we have another fail because I think you will be talking about the Kyung Changs with the three paws, the normal ones but they also make a very good one which even is better than the German three-paw one because it has the sheets of metal reaching up to the bow so you can't shim it because there are three parts, you need a three-bitted shim and who has a three-bitted shim who can improvise one in seconds but one nice thing we found out two years ago or something and published it on the congress as a zero-day exploit for handcuffs in Korea they still don't know it because they don't watch our videos there's one little glitch if you do the same thing which I did with the clues just like pushing in the bow almost a click then the three paws appear here without the sheets between so you can put in a straight tool hold them down and escape from the cuff so just in case you encounter one of those be sure to know that very very awesome are we glad Ray made the journey over here to talk about some of this so with all these techniques for having better cuffs kind of fail how do they make, how do police around here try to deal with the idea of oh I want a better quality cuff the two most common brands you're going to see in the US by far is going to be the most popular is going to be Smith & Wesson and then Peerless also are going to be pretty popular as well Republic Arms and then Safari Land you'll see around the world but it all comes down to money for a lot of these things so if you're going to spend less money on manufacturing you're not going to get as high quality a product most of the time so these are just a little better made just like any other lock they have less tolerances and the less tolerance you have the easier the harder it is rather to exploit the lock and then here are some examples with some of the higher end locks here now as you guys know if you've ever done any lock picking up in the lock pick village a higher quality lock doesn't always mean unpickable it just means you have to try a little harder so that thin shim technique that Ray was showing earlier where you actually have to insert the shim and see it kind of deeper by clicking yourself tighter you can do that on high quality cuffs like Smith & Wesson and Peerless if you're lucky and if you're not too drunk on camera here but yeah I can sink a shim down I just have to over tighten myself and you can still get out of those and that's open that's what standard cops can use in Vegas so if even those sort of techniques kind of fail if the idea of oh like you know we'll just make it tighter tolerance if that still doesn't buy you complete protection if someone knows any of these tricks what do they actually do in reality to make a standard cuff better well usually what they wind up doing is putting multiple poles in Ray had touched on this a second ago do you want to shim or keep me out of that side because I'm feeling kind of like a douche up here so putting in multiple poles like Dave could reach in and pick this right now because again it's a heavier cuff but it only has one Paul this kind so you know like a Hyatt's brand or an ASP a Chicago handcuff can you guys see that there are actually two Paul's in there now you might be able to shim that thank you pretty effectively but you can't reach in with like a pick or a paperclip or something like that you might trip one Paul but not the other and the same thing is carried even further with other brands that use like triple Paul's a lot of Hyatt cuffs from the UK have these the Kyung Chang's from Korea so again multiple Paul's in hitting some you might not hit all of them the Eul's are trying to tell us them tell them just about how bad ass the Eul's take this so we mentioned that just because you have multiple Paul's doesn't makes it harder to pick but doesn't necessarily make it harder to shim well the Eul handcuffs they went completely crazy with these this design they basically put a metal a metal blade in between the shim so you would need a split shim to get in there they went even further they have these flanges that crimp over and these ridges so when you even if you had a multi-tipped shim those flanges will direct the tips of those shims against a ridge or an edge it can net those shim the shim you stick in there will never reach those Paul's and also that metal blade going down goes through the entire body of the handcuff too so your key has to have a split in it to be able to reach around through the blade yeah the Eul Cuffs there's some of the nicest we've ever seen and for quite a while we couldn't get out of them none of our friends could get out of them even like CPA the 949 guys who are usually some of the nicest handcuff people you'll see like banging around parties with a bunch of cuffs on their arms they frustrated these guys too we didn't think anyone was going to be able to pick or manipulate their way out of Eul's I was impressed when some private scary security contractor type guys from one point tactical or at my house one day and they said oh you know I've seen I've heard of these these are kind of cool and with enough tinkering you know one fellow named Phil he was actually able to pick out now he wasn't wearing them at the time but it was a wonderful proof of concept where he said alright I've got this you know bent piece of paper clip and he just had to size it right and he got that to reach in around the blocking blade and trip both levers so we are like yeah whoa we were all impressed and let's celebrate so way to go Phil not a crazy high-tech attack but it's definitely one of the coolest things I didn't think that would be possible and that's why it pays to have really scary friends who are willing to just try it you're like nah fuck it I'm just going to give it a try anyway and sometimes you wind up with a cool attack like that now I should point out Eul takes it even further with their pro series their deluxe series in addition to having really nice silicone lining around the inside so you don't need the fuzziness if you want to have some fun with these they also have a much tighter keyway it's at a canted angle if you're wearing these proper cuffs palms out there's almost no way you're going to get into that tight keyway they have major shim protection now they've even added basically what we call a crushing wheel it's a spinning gear in the front that the pole can just ride across but imagine slipping a shim in there it'll just chew up and destroy it the shim will not get anywhere because of this grinding wheel it is again just the fucking the deluxe series Eul's are probably the nicest cuffs I've ever seen and they're heavy duty aluminum alloy so they're heavy duty but they're not heavy you can carry them like we are usually carrying a bunch of cuffs around and by the end of the day it feels like your shorts are falling off not with the Eul's they really do think of everything what was that oh yes one more if you know like crazy private security contractors from Iraq and stuff they will teach you a lot of really really wicked shit man this is Kelly one of the other guys from on point and has anyone ever heard of like Kelly have you seen any of these guys come around the show every now and then when you see the seer pick guys the seer pick this you know evasion and escape anybody do any seer training no they won't admit it there's like operators in the room but they're just not going to raise their hands so they will occasionally show you this trick and we don't like doing it because if it doesn't work it really really hurts and it you know they're out 50 bucks even if it does work but has anyone ever heard of just handcuff breaking not like you know crazy I'm a super strong man in the circus kind of handcuff breaking just leveraging physics just being able to make the chains bind up because you know how some cuffs are hinged a lot of departments have moved to that in fact when I was in Australia cuffs were looking at the cuffs like oh yeah here can you hold this for a second so this one this one cops like oh yeah you've got those you got those cuffs yeah you're coming from America right and he starts doing this and I'm like oh I know what you're talking about there yeah handcuff breaking is when you can twist the chains around and try to get them to lock up on themselves and then when the chains can't move and the eyelet can't swivel correctly you can actually just crunch down if you catch it just right you can try to snap the chain or snap the eyelet off and if it works oh yeah show so right now the links are bound together if I were to snap any harder this chain is probably great especially since this is aluminum yes and depending on the model of cuffs they may bind differently sometimes on some cuffs the links will even loop over the eyelet which makes it even easier I'm gonna maybe try it I don't know if we can try what are these cuffs costing I don't want to think about it man I've broken a few of these I've broken a few of them if you can keep trying to twist them around they're almost in a spot when I did you know like in baking shows there's one I made earlier what guys will do if you go to the seer pick table these diamond saw blades these like little diamond file here you can get the chains and you rough up the chains you can sometimes get them to bind up on themselves and I'd really like maybe if I can do it in one hand let me try it one handed here you're picking out on one side I don't want to sit here twisting them all day alright so the idea is to get the chain up on itself if you can get the chain up on itself and not let it twist around any further I can just kind of manually swing it into position almost I don't know if it's going to go I don't think it's going to go I want to keep talking while I just keep trying to fuck with this over here I want to try if we've got a quick second would you want to okay I've got a twist around and if I really don't want to hurt my wrist here and open that kind of hurts don't do that oh you want to talk about how I'll be alright in a second I just need more whiskey so yeah variations in designs different sizes of cuff can start to happen when you start introducing all these different features like sizing the paw differently sizing a different pack of paws imagine you know a cuff body that's really narrow like this one here but a key that might be from another brand of cuff where let's say there are multiple paws if you have a key thank you that's too wide this key is not going to turn in that cuff at all you guys understand that it'll fit in the key way whoo devil but it won't actually be able to move now we run into that sometimes especially when there's like a sea of cuffs on a table like all of our collections and we're like oh man which key went to which cuff maybe I'll get you out of those if someone's stuck in the lockpick village we're like oh wait a minute no I can't get you out of those wait who's got a different key over here that happens and it became such a problem for law enforcement that a lot of law enforcement supply catalogs started offering what they would call universal keys and usually these were just keys where the bit was cut down or oftentimes I think they were just keys that failed quality control and the bit was like way too small so then they're like hey we can sell these as universals alright it'll turn and it'll always fit how small the cuff is well that's fine that'll work really well but remember cuffs that have multiple poles like you know yules or not yeah yules would have multiple poles like these chiang chang in this video especially those triple poles when there's a lot of slop in there can you guys see this this is a universal key trying to operate the chiang chang and it's catching some of the poles but not all of them at different times so some go down others don't so it's probably not going to release these and slip like in between the poles or slip on and it'll like eat the key that happened like two years ago this poor kid we're trying to close up the lockpick village and he comes up to me he's like hey man can you help me out I'm like oh sure he's like some 12 year old kid right I'm like yeah yeah oh you got stuck in those yeah you need to be showing how to get out of them he's like no no I was in your lesson you guys showed me I'm like oh what happened it's like well you know I tried this key and the key won't move nothing will move and I went oh shit we have to go home with them on his arm we eventually like snapped the key off and then put a new key in but we kind of had an idea we said alright this is a problem the idea that you can't just carry around a single key that will always work even though they're all the same universal form factor we said alright what if at our last tool meeting of 09 the Christmas meeting I said everyone bring your cuffs we're going to Ed's shop Ed has a billion cuffs almost as many as Ray maybe I said alright everyone bring your cuffs I'm on a table measure all the cuffs measure all the keys measure them really precisely and start to chart out exactly how all these numbers crunch down we said if we look at because the key is like four dimensions you know the shaft has a thickness and the bit has a height and a width if we chart all these numbers together and compare everything including a few brands that need that split do any patterns start to appear do any ranges and tolerances start to appear as it turns out yes they do and there is kind of like a Goldilocks style ideal key we were able to find one it absolutely can be workable and now we can open up basically every kind of cuff that we have in this standard handcuff key form factor so starting out you know here are those crazy three paul Kyung Chang's which are one of the hardest ones that are always a problem sure enough works on those how about the peerless ones that are popular for a lot of police departments this is a colorized model 700 works on those how about the new generation the cheap peerless p010s that are now fabricated in Korea works on those how about old brands that aren't even really used much anymore these are Winchester's works on those I think this is a pair of maybe Chicago cuff company cuffs bang works on those here is a pair of smith and wessons again another really popular one here is the cheap little Valars the Valars that are such a pain in the ass that no one likes to work with you know I think we have a pair of one of the Korean Yule's just there south african company republic arms works on those next beyond that I think is the british by rbs this is the ASP used by a lot of tactical teams ASP cuffs works on those british cuffs from the hyatt's company the rbs company hyatt's has now become safari land based out of the US works on those does it work on the scotland yard rbs rapid cuffs yes it does works on those we just kept going down the line and even ray now giving us some german police issue cuffs works on those it works on everything and now if you want to have one well this is the key it's not really hard to make this all we found is that you need tolerances of machining you need to really be precise within about I'd say a tenth of a millimeter or less if you can machine things really close to these dimensions you can absolutely have a key that fits in all these cuffs you gotta be a little careful occasionally those triple pall cuffs you have to be kind of right in the middle manually it won't perfectly seat on its own but it's narrow enough to work everywhere what what the outer diameter of the shaft 3.5 millimeter the inner diameter 2.9 the blade itself should be 5.5 tall and it should be between 2.9 and 3.0 wide with a 0.3 millimeter down the very middle of the blade yes this will all be on the web if this is probably in your slide deck on the presentation CD now what we published this for is because even though tool did this research and we patented it we only plan on maybe selling this to law enforcement if there's an interest in the market we have no care if any of you want to do this on your own we completely believe in creative commons and you know copy left if you want to make these please do if you want to make these come up to the lockpick village we have a ton of a certain type of key that is ideal if you look at this chart and start saying alright I need a key that's this wide this tall with these dimensions immediately some keys get knocked off the list because they're just not the right starting dimension they're too big I'm sorry they're too small in some ways ultimately the Kyung Chang and the Smith & Wesson key are the only real suitable candidates for getting this key to be you know something you could shave down but look how much metal you'd have to take off the Kyung Chang compared to a Smith & Wesson really the Smith & Wesson key the new style Smith & Wesson key is freaking perfect you have to narrow the bit slightly it's already the right height then you drop a cut down the middle of it and right there there it is we have these Smith & Wesson keys up in the village we brought our calipers we brought our dremel tools and just freaking go at it make your own and then try it in like every one of these cuffs that we got here and see if you did a good job Con this very year yeah is there anything else that we forgot to add any of the other tips we wanted to say there the question was is that key the new thick key yes the one that has a thicker head stamped Smith & Wesson right on it I want to add that be careful with handcuff keys some states they're illegal to have if you are arrested if you're arrested and have a handcuff key on you you have to tell the police officer you have a handcuff key and have to take it away or it's an automatic felony if you do it in one place you will become an automatic FARC headline thank you 5 minutes for questions yeah so we even saved a little time for like 1 or 2 questions here and then we'll go into the Q&A room and follow it up and do a lot of hands on yeah man the question was does the split key how does that work with the triple pawl the split is small enough that you're never going to like lose the middle pawl through the split so it functions just as a wide enough bit to be able to triple pawl all three pawls if you center it so you'll barely be catching the edge of the outer pawl and the outer pawl and the middle pawl is just hit by both sides of your split bit oh yeah that's he was thinking about the three pawls with a blade but this is only this one kyeongchang I showed earlier this is blades it won't work on those but these are not used and as you see put a little and use a straight tool and push them all down so yeah and like the ASPs that you need to split you need to cut in the ASPs you need to cut in the yule but our key works in those ASP has a three pawl one with out blade and a two pawl one with blade so it works in both ways have you guys assessed the gacha handcuffs betterhandcuffs.com oh the gacha handcuffs are not on the market since company is basically out of business so don't be afraid of them I'd really love to see them throw up from a collector's point of view to have something round shaped key with an inner triangle so it's completely different but they're not on the market they're produced a few and they're out of business so don't be afraid of the gacha handcuffs from a design point of view using the gear it still seems completely takes away the fact of shimming it yeah you can't shim the gachas but you can copy a key I could 3D print a key for the gachas I guess anything else or should we start packing up all this steel and let you play with it next door one last question then we gotta go next door what type of dremel bit I found that the wheels you know those little brown wheels that snap and break all the time they're too wide they make a special diamond wheel they call it cut off way it's like 15 bucks that tends to be narrower that's a better one to use for the slot or like a really thin axel blade if you've got steady hands and not up drinking is that it are we good going next door okay we're gonna go next door thank you very much
