  • DO NOT TRY THIS ON KATANAS,ONLY EUROPEAN STYLE SWORDS

  • i wouldnt recommend sharpening a katana this way if you want to get the most out of your blade. no doubt this will get your blade sharp, but edge retention just wont be too great. you either want fine grit stones or sandpaper with a perfectly flat surface to give it a polish as well as a good edge. using this method on a decent katana is like putting $100 tires on a ferrari... get the most out of your swords guys, if applicable.

  • For the people who use these or know how to sharpen blades the right way...Can I use the method he's using with an accusharp? Like the comments said, take it nice and slow right? Or should I use something else? I tried looking for whetstones everywhere, and can't seem to find any for sale.

  • @Darkshadow222 And can I also sharpen katanas like this also?

  • I can use this on a katana?

    

  • Wow I thought you knew what you were doing. If your going to use the accusharp take it slow your fucking up the steal by heating it

  • can you make a vid showing how to sharpen using a more traditional method?

  • dont fucking use these holy shit

  • Does it work for a Hanwie scottish claymore?

  • Will a file ruin heat treatment?

  • @godofimagination Not if you take it nice and slow as to not build up heat while filing

  • I hope they realize doubling the thickness of the target increases resistance, so it's easier to cut through

  • @thesplitcell yeahhh sure buddy ...doubling the thickness makes it more resistant therefore it is easier to cut thru since it has more to cut and requires more force? yeah makes sense haha ...NOT!! ur comment made me laugh haha pick up a sword and try it yourself

  • i used this on my medieval sword and it isnt getting any sharper. its not getting worse but no better either. any tips?

  • Is that bamboo you were useing to test the sword?

  • would this harm a katanas originality by sharpening it this way?

  • @mrchockuls

    Damn....That is to hard I might just go to homedepot.

  • yes u can make it sharp,but will it weaken the edge ? coz its geometry of the edge is getting smaller and smaller .

  • Where can I get the stone to sharpen it?

  • dude your not supposed to sharpen swords like that, in time it will ruin the blade geometry.

  • What style Accusharp is this? Just the standard one?

  • imagine if this guy caught you trying to destroy his letterbox, i bet you he prays for that shit to happen, & on some nights will even attach plastic toys or matchbox cars by little pieces of string just to entice the little beggars to get close enough then, SAMURAI COP !

  • people an accusharp is not a proper katana sharpener. for a katana a recomend usind a whetestone.

  • What is that target made of?

  • way to ruin your sword idiot. i hope nobody has tried this on a good sword.

  • @gtarbmx Yes, clearly Paul is an idiot who knows jack shit about swords. So tell us.... where is your website devoted to reviewing commercial swords?

    Cough up that URL so we can all go there and see how much better you do it.

  • @WurledPeas i don't remember what i wrote but nonetheless accusharp is not a good tool for sharpening swords unless it matches your edge perfectly. and even then it's still not a good idea. and as for the url, just look up any other videos on sharpening, you will find much better advice.

  • @roflheh i use 2 stones given to me by my grandad. 1medium grain one extremely fine. No way do they get them razor sharp but they do the trick. plus instead o chopping someone in half when they piss me off, i sharpen my collection

  • Just so I'm clear, you spent 20 minutes on a sword, then cut 4-5 inch diameter tatami easily, and there are people below saying you did it wrong?

  • my sword is 4 sided tho its sharp but i want to make it more sharper

  • It stays sharp for a little while but I wouldnt recommend it with high end or katana swords. cheap fantasy swords, yes but not something worth some good money. and sharpening is relaxing to me. I could spend a good hour sharpening my katana. It's kind of therapeutic to me, but to each his own. I'd save the accusharp for the kitchen knives.

  • @tapout320 can you tell me what you sharpen your katana with please?

  • will you be testing the new cold steel italian sword it looks awesome

  • Using the accusharp on a series of my knives, I notice it does one thing, and that is to create this clamp style edge. The edge does not get polished but does leave it a bit sharp. More of utility kind of an edge. The edge will have tiny micro serrations in it. But using this sharpener on a sword is fine, only if you wish to give the sword an entirely new edge that is compared to a knife. Like what some user have said, I would stick with just the water stones, or wet and dry sandpaper.

  • im buying an accusharp now.. i know its not the best. but, i dont give a fuck, i want my blade to be sharp. thanks.

  • If you love your katana do not do this...

  • whats wrong with this... i got a katana and am considering to buy an accusharp

  • @aznshir0 An accusharp should ONLY be used on european style blades. Japanese swords must be sharpened using a series of wetstones.

  • @ShamusMacGuffin Explain?

  • @MonoxideChild1219 Explain what? How to sharpen a katana with wetstones? That's like asking a virtuoso violinist how to play the violin. It's an art in and of itself. Just take my advice, if you have an authentic Japanese katana with a REAL hamon, DO NOT use an accusharp to sharpen it. You'll ruin it's value.

  • How so? It's much easier, besides the fact that it's not the traditional technique.

  • The edge of a Japanese sword is the hardest part of the blade. It's razor sharp and is tempered with clay, hence the wavy line or the hamon. An accusharp SHAVES the steel away and since the edge of a Katana is thin already, you'd comprimise the cutting ability of the edge and wear away the hamon. Sharpening it with wetstones merely BUFFS away imperfections, bringing out the natural edge created by the clay tempering process.

  • The blade only becomes "razor sharp" after sharpening, not after hardening. Accusharp may be harmful to use because it heats the edge and can ruin the tempering, not because it "shaves" the blade. And what does it mean, "shaves"? Both a grinding stone and an accusharp remove excessive steel from the edge, making it thinner, sharper.

    When sharpening with the accusharp you should not over-heat the blade and correctly adjust the angle to form the right cutting bevel.

  • It WILL destroy katana edge geometry by creating a secondary bevel =( Works fine on European style middle age long swords though =)

  • @MrTefached who cares, a flat geometry is all around simpler anyway, bullet tip blades are overrated, only benifit is they dont roll or dull as fast.

  • @flufebunekilr But if you have a combination of a convex grind with a flat geometry for the last 1/16" of edge it'll cut like a club. I know, because I've actually used an Accusharp on a katana. It's something I am NEVER going to do again.

  • @MrTefached as long as i can cut straight line in one swing through paper im good to go... all my katanas are perfectly flat after i butchered them, they're deffinitely no work of art but they more than get the job done :)

  • @MrTefached So you would say not to use it on just a katana because of the way the tip is? Soooo would it be safe to say that any blade with a tip similar shouldn't be sharpened with an accusharp?

  • Comment removed

  • @QouqaTube no for the shape of the edge of the katana itself

  • i have a katana, with this tool, do i run it along the full side of the blade then do the tip?

    do i use lubrication oil with it?

  • anyone who uses this on a REAL sword deserves to be punished!

  • do not sharpen an expensive sword this way...i use my accusharp on my cheapest blades... but i gotta say, its pretty damn good...from blunt to sharp in a matter of minutes...

  • hey one question im gonna get a sword wat kind should i get first shirasaya or just a normal katana

  • Start with a katana. I know it's tempting because of the big price difference, but shirasaya pose some inherent dangers due to the lack of a guard.

  • a shirasaya is what valuable japanese blades are kept in, they are non laquered wooden saya (scabbard) an tsuka (handle) designed to let the wood breathe to prevent rust damage to the valuable blade, the tsuka is held to the nakago (tang of the blade) by one mekugi (securing peg), not designed for combat use, normally a katana tsuka (handle) is fitted with 2 mekugi pegs. If your lookin for a katana of good value by a hanwei practical plus katana or something like that :)

  • The accusharp DOES GIVE A SWORD A PAPER-CUTTING RAZOR SHARP EDGE.

    It is completely functional for sharpening a sword.

    It DOES however make it obvious that it had been sharpened in that manner.

    What I would recommend is using the accusharp, then using fine grit sandpaper, or a Siageto water stone to polish the blade and bring a more refined edge to the metal. At this point it has nothing to do with sharpness, just finishing the edge for appearance.

  • LOL, stone vs. diamond vs anything else...

    It is the Steel, the angle of the grind, and how fine the end grind is that matter. Not what you use.

    I have a hand and a half bastard sword I used to cut down a metal shed, two cd-rom drives that irritated me, and a 1/4" case hardened chain. I used a 60 degree initial wedge for the rough grind, then a 35 degree finishing grind and used a leather strap to fold off the feathering for an edge i could shave with, yet strong enough to cut heavy stuff.

  • no no no this just ruins a blade best ways are with the stones

  • Would it work on an axe?

  • Wise to sharpen a katana this way?

  • I use a high speed bench top belt sander with a very fine grit belt, followed by a cardboard wheel with fine diamond compound on it. I have used it on my 2 Cheness katanas, and all my other swords. They all will shave hair, and cut bottles like lasers. You have to get the cardboard wheel and diamond compound from a knife making supply. Hope this helps!^_^

  • i heard that when you sharpen with grinder and/or other machine, the knives don't stay sharp longer than with a stone

  • Wow, this the first time I have heard that:-) I think it would be a combination of the angle of the edge, the type of steel, and what the sword was used to cut. I do have a lot of admiration for someone who can bring a blade to shaving sharp using stones, everytime I tried to use them, the blade would be as dull as a baseball bat:-(

  • could you pls tell me what would be good for me to use to sharpen my katana i would be EXSTREMELY grateful

  • for a katana use a stone for a medeivial use the accusharp katanas lose their balance with the accusharp but the accusharp works great for medeivial swords

  • Sorry but what you are doing is the worst thing anyone can do to a sword...

    ASH

  • Agreed. Total clown. Lazy also.

    Seconded

  • Well yes, if you cut like a failnoob, you do see that. Blunt swords can cut tatami.

  • Do you sharpen all your swords this way or do you have another tool you use to sharpen???

  • Comment removed

  • Please, don't do this! I messed up a nice Del Tin sword with this thing!

  • So you sharpen it along the length of the blade from hilt-to-tip? as opposed to center-to-edge? And what exactly did you use to sharpen it? I have a blade myself but I am so antsy about using it that I only practice my stance and strikes with it, I don't have the heart to actually try it on anything.

  • Please look at the sword - it's not a Katana... ;-) I don't recommend these for Katana, but it's an ok method for a blunt euro (not ideal, but quick and easy).

  • broad swords dont have a hamon so it really doesnt metter. you martial arts peaple (and me in them) thinks every thing is about martial arts.

  • what is an accusharpener and where do u get it? i have an east indian sword that needs sharpening really badly so do u have any advice to sharpen it with something else?

  • Sir, is that a viking sword?

  • Actually that one is the DSA 'Medieval Knight Sword'.

  • Is it true that sharpening a sword makes it more brittle?

  • if you do it too much then obviously because when you sharpen a blade it is making the esge thinner then it is going to make it more prone to chipping really you dont want your katana to be razor sharp because of this and because cutting something is more technique than sharpness and obviously if you were using a proper sword this is really not the way to go the accusharp is designed for kitchen knives not swords

  • well, this all depends how you use it and what type of sword, lets say long ago samurai warriors a katana, in theory blade to blade contact might or may not chip the edge, but it wasnt used that way, the edge where for slashing and the other side for defending.

    broadswords in reality where never sharp, in the years of crusades and all that stuff , others wore chain mail, so the broad sword was used to break bones rather then slice. do they got dinted not chiped

  • Broadsword is not a correct term for medieval weapons. And yes, crusader's arming swords WERE sharp, it doesn't make sense for a sword not to be sharp. If you want to crush you take a mace, a sword should be sharp to cut and thrust effectively. Also, lamellar armor of the samurai (nope, they were not fighting in kimono like in the movies) is even more durable than the chainmail of crusaders, so, using that logic, katana is a bludgeoning tool as well.

  • the broad sword, the ones like 5ft long wasnt sharp i know this for a fact,  it was used to break bones because the sharpness of a blade would not get though chain mail, and if it was sharp it would chip to pieces and then break in half thats the other reason

  • @kaleluk31 i was under the impression the the blade would cut you just not super easy like a real samurai sword. but the tip was were the sword action came from. for eg you would use a sword edge for blocking and stab for attacks. if im wrong let me know.

  • @samuraimoose i have no clue which sword and what era you are referring to at the moment

  • Comment removed

  • @kaleluk31 was thinking along the lines of crusades era and a long sword as well as a broadsword, im sorry i was too tired when i posted that should have stayed off the keys LOL

  • ahhh the crusades yes swords where shorter and in this purpose yes they would be sharp

    for lightweight battle , slash at the legs then bludgeon the face because the upper torso was chain mail designed to withstrand a deadly blow

    but that's where the long bow archers came on to it.

    think of the battle of adgencore

  • British had good archers, hence where the sticking 2 fingers up at someone comes from, archers when captured by the french would get there 2 bow pulling fingers cut off so they could not pull a bow no more.

    so i battle British archers would taunt french and wave the 2 fingers at them saying you wont get my 2 fingers or along those lines

  • @kaleluk31 Actually, that's false; the whole 'two fingers' thing is said to be archery-related, but it was around long before then, I'm fairly certain. I don't know the true origins, just that it wasn't british archers taunting the french that they still had their fingers.

    Thank you, QI.

  • @MGlBlaze I guess we will agree to disagree, but if you would like to find reference to how i said it, go to Wikipedia and look up V sign as a insult then look up the paragraph on "origins" and it will say exactly what i said

  • @kaleluk31 Yes, I've read the article; "According to a popular legend" is really the bit that gets me. There's also "Indeed, there is no record of this explanation for the V sign before the 1970s, and it seems to be a popular myth." but that bit is marked as 'citation needed' so that could go either way.

    In any case though, agreeing to disagree is fair enough with me. I just get a little touchy when people present as fact things that are of ambiguous or uncertain nature. That's just me, though.

  • @MGlBlaze Wanted that line to be "things that -I feel- are of ambiguous or uncertain nature." there. Hit the character limit, sorry.

  • @SwordBuyersGuide Why does the cross guard look different than the pictures and other videos of the destructive testing?

  • lol it works pretty good on my 2 inch knife

  • he actually used a knife sharpener not a west stone

  • I've ordered one of those earlier this evening. All I have at the moment are a few knives though.

    T±T.

  • will this work on naginata?

  • I really disliked the accusharpener alot, I am working on a stone/sandpaper/micromesh way of polishing tutorial. check it out on my channel. the pross will cover metel filing, stone grits 400/800/2000/ then sand paper grit 320/400/600/1500. and polishiing and sharpening with micro mesh grits 2400/4000/6000/8000/12000. thats a blade with a 12000 grit sharpness factor. I expect to be finsihed with the whole tutorial in at most 2 weeks " it takes a long time " part 1-6 out of 12 or so are up now.

  • het where do u get the sharpening stuff

  • i brought 1 of these the other day thinking it would give a nice sharp edge instead it gives u more of a rough almost serrated edge id def not use this on a katana it complety roots it i know...now im trying to use the trad way to smooth the edge out

  • Yeah, I don't recommend it for Katana.

  • have u got any ways that can help me get the edge back? any help would be great thanks

  • but you are using this for a katana in this video?

  • No, it's not so good for Katana.

  • What do you recommend to sharpen a Katana?

  • You have to buy sharpening stones made to sharpen a katana. They are expensive but they work.

  • @SwordBuyersGuide Then what does work for katana's or Ninjatō's?

  • @XxIosephus007xX Water stones and patience.

  • the katana i am working on in my video was an accusharpener victom. it will get it very sharp yes but it will mess up your polish and edge geometry instantly. my vids will show you how to restore it to a mirror finish

  • ;\hghjgh

  • do those sharpeners work the same as Boker's Vulkanus sharpeners for knives?

  • That's cool and everything but I couldn't tell what you were using.

  • It's not good sharpening for Katana i think. You should sharp all the cutting edge, not only edge of edge :P

  • Where do you get your tatami mats from? I got to get me some of them for my Cold Steel great sword. That thing is a MONSTER!

  • Try either 'Keen Mirror' or 'Mugen Dachi' - best mats on the market.

  • don't trust those sharpeners.

    i'll stich to bench stones.

  • at first, i didn't trust those sharpeners... now i do!!!

  • Nice vid :)

    I have a fairly cheap, but genuine samurai sword :) I was wondering - how can I make it deadly sharp, yet also keep some shine to it too? Thanks in advance!

  • There is a sword care and sharpening guide on my site: sword-buyers-guide DOT com.

  • I'm about to buy a Musashi Shirasaya like the one you have only in black. I'm wondering, what should I use to sharpen it? What exactly did you use to make yours so deadly sharp?

  • Nothing at all, all the swords tested on SBG - are used straight out of the box. The only swords that have been sharpened are stated as such in the body of the review - none of the Japanese ones have been touched up at all.

  • Oh... so if I ever needed to sharpen it, what do you recommend I use?

  • 3M Abrasive paper and some water (hard to describe in a ytube comment box. XD). Have a look at my site 'Sword-Buyers-GuideDOTcom' under the care and sharpening section. :D

  • Your site is a lot of help,thank you so much Paul =D

  • No worries, glad to be of help. :-)

  • if i do get this ill test it out an my crappy wallhanger first, then move on to my more expensive stuff.

  • Always a good idea. :-)

  • stupid question will the acusharp work on a katana ?

  • Yeah, it will (on a cheap one that is). It would be total sacrilige to use it on a real one. But it works - though more advanced methods are preferred...

  • This is helpful.

  • some advice for people wanting to sharpen katanas... use a belt sander to get the geometry back to optimal performance and a sharp edge and use some polishing stones or 400-1000 grit sandpaper to polish it as well... and questions and ask me on my profile

  • why do that when you can use the accusharp!!!

  • A belt sander will cause the blade to heat up a good deal and you could possibly remove some tempering. You would have to have a quenching bucket by you at all times and never let the blade be in contact with the belt sander for more than a few seconds. Better to just learn to do it the right way or better yet take it to someone with the ability to.

  • i guess the samorai-shark is just a ripoff of this, since this one works so well. My SS sucks

  • Finally someone actually tells how to get it good and sharp. Thanks man!

  • Kudos! Got to check out that technology.

    I am putting the link to this up on my "Free Companions" forum.

  • Thanks!

  • nice paul good job man con u sharp katana like that ????

  • Hmm, well - you could. As you can see, it works well enough for cutting tatami, etc. It would change the edge geometry, and the edge won't look as nice, but in theory - its doable...

  • Hi Paul. I heard that the accusharp leaves the blade kind of grainy and coarse, is that true?

  • Yeah, its far from perfect - I have explained it all on my site (this is just the accompanying visual aid).

    But if you don't know how to sharpen a sword any other way, or are just looking for a quick fix - this is the one...

  • Will it hurt the blade or something? That is what some people on Sword forum are saying.

  • Well, I wouldn't use it on an already sharpened sword or an expensive one. But for sharpening up a completely unsharpened sword (i.e. Windlass, Darksword, etc) - works great.

  • What about a dulled tenchi, or something like that?

  • yeah it should work pretty well, I used a sharpener similar to the accusharp on my sorta dull shura and it made it pretty sharp. The edge was rouhg but it cut paper easily. It shaved away the etched hamon but there was barely a secondary bevel. it is a great option if you don't want to learn how to sharpen a sword the traditional way.

  • I see....Oh well :D Thanks man

  • nice
