a samurai will be so angry

man, i bet this was frustrating responding to these assholes in the comment section over the years. Cracks me up. all these master blacksmiths, sword sharpeners/polishers, masters of kenjutsu etc. plus i bet their swords are cheaper than those and they cappin like they have something special when its a cookie cutter katana made in longquan just like ours lol - self awareness is lackin in them. i just wanted to give ya props for being a trooper despite the window lickers

On the cheap swords yes, okay. It puts a bevel edge on the Katana. To correct the antique (if someone ever wants to do it) it will need lots of metal removed to correct it during a correct "polishing."

what do you use for sharpening (the name of the model of tool you are using in the video)?

good too see you can sharpen a katana with this. I have an inexpensive carbon steel one that needs a good sharpening

Have you tried sharpening the last sword you showed us yet? I am thinking how much it will degrade the good looks of a proper water stoned sharpened edge? I have 2 katana swords and I made the same miste as you(luckily on the cheaper one) I Used that stupid accu sharp or whatever. It scratches up the edge more than I would like.

Where from i can buy this equipment?

when this idea first popped in your head to do this, I bet you were like," Oh yeah! " Great idea, btw.

Yeah I can see the edge where you sharpened . when you turn it and the light hits the blade just right then I can see it. How much is one of those sanders ?

Very informative video. Although I don't recommend doing this to a high end katana (mainly for cosmetic reasons), it looks like a quick and inexpensive method to put a good edge on a backyard beater. My only concern is what the heat, generated by the friction of the belt sander, does to the hardness of the edge. Doesn't it unintentionally temper the edge and lower its hardness?

wow nice vid i have run my cas hanwei tactical katana through my worksharp i was afraid it might ruin it but u convinced me man i cant thank you enough, of course i played with the guide bar on my worksharp so the bands keep popping off so i got to get it lined up right again but i thought i was stuck with a $400 5160 steel stick cause i dont know how to sharpen a katana

How do you keep it perfect with out leaning to one side?

where have u it buy

Hi! I just bought the work sharp ken onion Edition, and I want to sharpen my katana. What degree (angle) would you recommend me to use?

Just happened on this video, Joey. I'm always interested to see the Work Sharp in action. I had the chance to pick up an expensive and rare pedal (Skreddy Screw Driver) to use with my Teles and Strats. Couldn't let it slip through my hands. I bought it from a dealer in Southern California. It came dear with the Canadian dollar what it is at exchange. I've been after this pedal for more than a year. Unfortunately, I've been set back to waiting on the purchase of the Work Sharp - think I'll go for the Ken Onion model.

that really hurts, a Katana is not grinded but polished to be sharp

Hi, I'm interested in getting one, i got a 200€ or so katana, brand ten ryu, not sharp at all, so if i use that thing, i shouldn't use the guide for the angle is that it ?

Can you correct the edge Polish even if the ha isn't correct, kind of ripply. I bent it so there's warps

Thanks for the video. I have a katana that I payed 450 for and love it and I want to do some cutting but was worried that I would not be able to sharpen the blade without ruining it. great little belt sander and I love the guides.

would 20 degrees be good for longsword as well or should I go for the 25 degree attachment that it comes with?

What angle did you use on the guide?

nice sword i wondering does the cold steel folding knife have the strenghth of a kitana

my katana needs a sharpening too got 3 small dulls or chips i dont know :/ you using 20 degree right?

where i can find that think you sharp katana???

Can you sharpen just the tip on the machine or no ?

A sanding belt cleaner or sanding belt cleaning block may be handy.

This video makes me cry

secondary bevel.

That musha has wire brushed Hamon. It's only for looks. It's 1045. and they are heat treated FYI.

Just sharpened my Cold Steel Katana. Crane 800 euros or something. Taped the blade from scrathing but is was not even needed. My Works Shaps is the basic cheap one, something like 90 euros. Worked great! Tried it first to few knifes from fletching knifes to butterfly knives etc. :D All came up pretty more than good. Scaling 1/10 i have to say it always a solid 8. Even swords it is and 8. You can hand sharpen better but you really have to put time, skill and effort to that one. Now i just use the machine and hand sharper more if it is needed to real razor sharp. Do not get me wrong 8 is sharp as hell and sharper than literally 9/10 of you can ever sharpen a blade by hand.

You gotta sharpen it like a traditional Swordsmith (sarcasm do the fuck you want).

I must be real stupid of something cuz i received mine and used that one of my blade and still it can't even cut through paper...

can i start and only use the 6000 grid?

gr8 video thx!!

Actually, you are supposed to raise the handle, or you DO blunt the tip. You are supposed to match the curve of the edge. Go watch Doug Hosler's videos, he works for the company doing instructional videos.

I think im going to take the plunge and invest in one of these bad boys

no hamon doesnt mean its not heat treated, it just means there is no differentiam temper. belive me they are fully heat treated. its also likely 1095 hcs

Does this work sharp genuinely work on katana? I have a whetstone and have tried to sharpen it by free hand but i've only scratched my blade rather than sharpen it. so i was wondering if i can use this work sharp instead.

Cheap, quick and katana in the same sense ?

The last samurai sword looked like a mechanical wire brushed hamon, while the second one with "factory hamon" looks like it was a chemical etched. Two of the cheapest ways to imitate a hamon. I'd be willing to bet you could find a good combo between the work sharp and a Japanese water stone to break the top edge made by the work sharp. While I would use this on my through hardened cheapie cutter, I would never let my differentially hardened katana or Damascus touch that machine. Once the blade edge geometry is ground away, it'll be hall reshaping it to completely smooth continuation from edge to spine. The katana is shaped like this to facilitate low drag through your cut. Good video and decent collection you've got.

This is a video of how not to sharpen a katana. You just totally screwed up the geometry of the blade.

buy the belt kit for the ken onion edition and trim the width of the belt to size and you will crap yourself about the sharpness.

now what do u need the sword again for.?

What's that machine he's using

Seeing the lining on the blade, it seems not japanese made.. Its to perfect the lining..

I have the exact damascus steel sword, its a good cutter, chinese made

Sharpening Katana's on anything but wetstones is herecy. You don't need to buy the most expensive ones, even leatherstrapping is less rape then this.. i would never let sandpaper anywhere near my Katana.

I got a 200€ 1045 carbon steel katana. It's not all that sharp and your way of doing it looks promising. I got the tools, too. What worries me is that I would scratch the blade. Any tips to prevent that? Great video

I just got a sword for about 95 and it is the same black one you have lol. The last one shown that is

Caramba guerreiro muito boa a máquina poderia me informar onome da mesma em português ?

just a tip for Japanese blades: they all have an asymmetrical blade geometry. please don't use a work sharp on an authentic katana if you have one. thank you sir. I'm not trying to be rude, but the swords are designed to be used a spesific way, and changing geometry does effect proper use.

1000 like for u

Our swords say the same thing the third blade you showed i have 2 that both have the same mark if im not mistaken it says "ancient times" its Chinese

If you havent tested them after doing this how in the world could you claim it to be a good sharpening technique. If this thing cant keep a 15 degree angle then it is ruining your katana. The katanas edge should be 15 degrees no more no less.

Said it’s not a Japanese custom sword or anything... BUT he’ll probably sharpen that one too🤦🏽😂😂😂 jeezus bruh.

red capillaries rising to the skin...

Hold your hand behind the blade or use a piece of paper so the camera can focus when you do a close-up. Every single knife video they try to show a blurry close-up it's very annoying. if we can't see the edge we might as well not be watching.

Do be careful sharpening it with a belt grinder, you might lose its edge temper

5:50 !! I always thought this sound was a cheesy effect in Hollywood movies...

perfect for crushing your Coors light cans!

fake katana see that wave in the swords its so perfect

i got a katana for like 50$ full tang razer sharp real hommon leather tsuka and iron fittigs

You can't sharpen a katana like this you just destroyed the cutting edge .to get this sword back to its original state would take days of hand sharpening now which s what you should have done in the first place . There is no tapered Edge to a katana the blade runs to strate down to the Edge.

I use a 1x30 belt sander for my swords. The results are great, but secondary bevels just look plain butt-ugly on swords. Not a problem for users, but for a more artistic piece I'd stay away from it.

weaboos are flooding in this comment section.

you fool, it's a niku on the blade now...

How to create a chopping edge overtime. 😏🙄😎😤 The lazy way is never good.

A katana is to be water wheel stone sharpening so the heat treatment on the edge is not fucked up by sharpening. That's how they do it in china and that's how they do it in japan. Using a grinder or a sanding belt will greatly damage a sword or knife, reducing its functionality and value tremendously.

11:29 oh my Buddha you just destroy your katana structure ( shrap side) and your Hamon wave by using that machine.

Thank you, though I've known that since before I bought them. They're all garbage blades to me now.....thanks.

Nooooooo! 😲😢😫🤦‍♂️

i dont even use that junk ass guide anymore on my worksharp i hate the convex edge it makes. i like the V-edge or compound bevel edge best. and you wont get them with those guide

liar liar liar liar liar

Waow...a japanese skilled swordpolisher would kill him self if he see what you doing.... That is a total shame... I definetley DONT like the way you treat a katan....its a shame...
