konron 9260 katana tested too the bone cam2

[defza]

That's what happens when you hit something with a blade instead of cutting it properly.

[arvbur09]

omfg you broke it = OOOO

[Mathaius833]

so 9260 isnt indestructable

[KenMacMillan]

It almost looks like you hit the table as well as the bone.

[Madmann135]

Though I consider the last part painful to watch it does show that a 9260 spring steel katana is not indestructible. Yes it can bend 90 degrees laterally and return to center but she is not indestructible.

[Techead78]

Maybe make a Katana out of cow bone instead of steel?

[kenshiliamateseru]

Kids in the background:( that could have went bad ha ha and you almost nut tsukied yourself

[lordpoee]

I have never in all my days have seen any katana walk away from a cow femur without a chip, bend, roll or break. It's a cow femur. So if your katana cannot cut through a cow femur without breaking, bending, rolling or chipping, don't feel bad....Samurai never fought many cows...

Hi Nicky,

Nope ik ken die smederij niet. Het klinkt als een standaard low budget cutter.

Let op, niet alleen de staalsoort is belangrijk, ook de heat treatment. Deze is eigenlijk nog veel belangrijker. Kopen en uitproberen. Vele low budget zwaarden zijn flink stevig en leuk voor backyard cutting.

[TheNickyvanveen]

Zo, die is kapot..

Hey ik vroeg me af of jij misschien iets meer afweet van de smederij 'fujiforge'. Deze smederij verkoopt zwaarden voor 175 euro en claimd dat deze van 9260-c gemaakt zijn.ik kan er verder nog geen reviews over vinden sinds ze best wel nieuw zijn. Ik hoop iets van je te horen, groetjes nicky

[NeroNekoHeart]

Bone is actually 5x harder than steel, because even though hydroxyapatite has a MOH hardness of 5, the calcium strengthens and hardens the minerals, making bone harder up to the MOH hardness scale of between 6.5 to 7, while steel is 5.5 to 6. Combined with the fact that this cow bone is more than 3 times the thickness of any human bone, this is not surprising. Nothing is going to slice through that with one strike.

[ZentetsukenVII]

thats crazy, i cant seem to fin the brand konron, id like to take a look at them. and does anyone know where i cn buy W-2? ive been wanting to set up a forge and start learning the basics of blade making

cool vid man, sorry about your sword. turned into a wakizashi and a tanto huh? lol

[trialsrider001]

i didnt see that coming.get out the file and make a new tip

[Oresticus]

You are supposed to be cutting through the bone, not trying to smack it out of the park... Hey bro, your samurai days are over... But you're going to be one hell of a baseball player lol. No offence, it just looked like you were trying to hit a home run and i'm guessing that's why your sword broke.

[Dreamland2100]

The cow femur were 2 o r3 time thicker than any human femur.

[mickkidoTV]

damn.. for tht b n 9260 spring steel hope it wasnt a $500+ katana.. best stick to tatami mats n bottles..

[SiN9Ty]

I think that blade wasn't temped after it was quenched. 5160 spring steel might take edge damage from that bone but should not snap like that. It looks like its almost as brittle as stainless.

[Highlandersforever]

one of the better steels for swords is L6 I have blades in this steel and there flexible but not weak either the reason to use a more flexible steel is so the swords dont take a permanent bend on bad cuts but if not differencially hardened the right way the blades can easely break, just a shit sword is all

[0bsidianos]

het zwaard kan dan niet door koebot heen.

Het kan volgens mij wel zeker een arm afsnijden hoor!

[d2eux]

damn dude, hope you didnt pay too much for that

[kalechinees]

using spring steel is a just way to compensate badly quenched blades... The blade will be more flexible then normal carbon blades.

The carbon blade would break sooner so it would need a better hardening / quenching and thus a better blacksmith to get the same quality.

[255Knights]

Spring steel is great for armor what I understand, but for swords I do not think so. I agree, if the blade is too flexible the main down side I can think of is that a good blow or hit could push/slide through your guard or block...

The best steel I can think of is Tool steel or use Pattern welding...

[255Knights]

I mean to say the best steel to make a sword is Tool steel or use Pattern welding... Others are ok if you know how to make them good...

[moman007]

I have a Hanwei Katana, Differentially hardened, cuts through anything with no problem, Incredibly durable.

I have a Cheness 9260 O-Katana, cut random stuff with it (Branches, tires, metal). One bad cut on a peice of metal and it snapped in half.

Differentially Hardened Katanas are superior to 9260 Spring Steel.

[ind20000]

One bad cut on a piece of metal and your Hanwei would be destroyed as well, dif hardened are still better though.

[moman007]

yup, no sword is indestructable

[gracer99]

why cant spring steel be differentially hardened? i mean, i guess i don't understand the chemistry of it.

[moman007]

just so u know spring steel can be differentially hardened. Check out the Cheness Kaze Katana, differentially hardened spring steel katana.

[EddieCubillo]

In order for spring steel to absorb shock the way it's supposed to, it has to be be properly monotempered, which means evenly hard throughout the blade, if dif. hardened the blade would be too brittle, and also lose it's ability to go back to true form when bent. That's why.

[tomfunfun0530]

i thought it was going to cleave through the bone that sucks im dissapointed i thought a katana could cut somebody in half but i knew a sword cannot cut through bone

[L03k1]

Why so aggressive? :P Great vid, thinking about buying a katana myself.

[tokugagua2008]

the katana hits the wood,it`s a bad model (in cheness , they forge the swords very well)

[Espen4555]

No offense but reason blade broke isnt cause of the steel, is cause he obviously dosnt cut completly straight, its quite obvious when he hits the stick <.<

[bmw335hdk]

oh my God!!

So, what is the best steel to make a sword better than 9260 steel? I almost order Kaze or yamakami katana from chenness, they make it with 9260 steel then I'm just wondering if the kaze can be like this...

Would you mind to let me know what is the best steel for making a sword, if it's not tamahagane nor 9260?

[255Knights]

The best steel that I can think of is tool steel. But there are difrent types of tool steel just look them up...

[katanasam1]

Handled flesh and bone? This was a cow bone that was considerably thicker and harder than any human bone. I'd expect many if not most katana to break or bend from that. For everyone else who said it was a bad katana - show me your katana not taking damage or breaking from that. Of course the skill of the user is an issue too but nonetheless katana are not indestructible.

[isaacgcallison]

That should have easily handled flesh and bone! HELLO! It is what it is designed for! My chen practical handled bone and flesh without any damage, and I have been using it for years. i have accidentally hit steel and concrete with only minor damage. Bad sword, not bad owner!

[kenpachi316]

amazing! looks like im going to avoid konron forge.

[eblackmore]

If you want to chop things up in your backyard buy a cheap machete. That way when you inevitably damage it because you are abusing it, you arent throwing away much money. If you absolutly have to have a katana to demolish things, then I guess throwing a bunch of money away is the only thing that will make you happy. Its your money so who cares what you spend it on. Its just a shame when someone abuses something nice (Or tragically, something old) and breaks it.

[famousmanbearpig]

quit your crying. you just said its his money, so let him be.

[eblackmore]

@famousmanbearpig

Aww. did I hurt the little manbearpigs feelings with my harsh assesment of your little friend?

[famousmanbearpig]

@eblackmore quit your crying. you just said its his money, so let him be.

[Aliensoldier]

omg i really didnt think that was going to happen! lol but yeah still a good sword

[Hyoujinsama]

I agree with chisacat. I can see a bent blade, broken edge; but a complete snap on a cut like that? Bad heat treat. Sadly, a lot of cheapies are the same.

Also, just to clear things up: Modern made nihonto range from about $4000us and up. Using modern, purified steel, folded blades are no better (and in fact may be worse) than monosteel due to possible incomplete layer welds. The key is not in the steel or how it is forged. It's the heat treat that gives blades their strenght and resilience.

[chisacat]

I seriously doubt that this blade was normalised after hardening for it to break like this - too brittle , not ductile enough

it should have taken a set only - not snapped at the monouchi like that - I also mean no offence , just my 2 pennies worth -

[nederveen1962]

No offence taken.

If I would have the money i would buy a real shinken. Ore a katana made from tamahagane.

But this was just a "heavy" test on a simpel katana. One you can use in the Dojo and for backyard tameshigiri. For those things it's a katana well worth it's money.

[Jarno1510]

Bone+cheap fake katana = cheap fake waste of money tanto...

[nederveen1962]

Try it with an folded or even a damascus katana, and you will get the same result.

Even a Viking Axe had trouble with this bone.

The blade of the Axe folded.

Just for the record a $300,00 + katana isn't a cheap fake katana.

[Jarno1510]

$300 is nothing...

Indeed, the bone is very large. I wonder why you would even try to curt it with any sword. Obviously a high quality cleaver in a skilled butchers hand would have trouble with it.

A real (newly forged)katana goes $10 000 or over. The mechanicly pounded mass constructed, but still concidered sanmei katana are about $3000 to $4000. I don't know where or by whom the Konron 9260 is forged, but according to my expertise it is a cheap ($300) replica (=fake) katana. I mean no offence.

[TheBoy765]

You may not be trying to offend, but that is a fairly smug comment.

Most people do not have $3,000 sitting around to spend on a backyard sword.

There are plently of monosteel sub $300 katanas out there that can stand extreme punishment. They are not meant to be traditional, just entertaining and durable.

[TheLoserKingdom]

@nederveen1962 Huh? How much money? $300,000?!

[tollios6553]

there is nothing wrong with buying a fun decent katana that can cut some things.
