$3 Rusty Japanese Knife Restoration

Japanese Knife Restoration Video
I just found another rusty Japanese knife from Japan recycle shop near my house. I already knew that this kind of knife is difficult to restore, but I really love the knife quality. You can see the quality test at the end of this video.
The sander paper I used P100, P150, P220, P320, P400, P600 and P1200
I used normal stone and wet stone 1000 and 3000
I hope you find this video useful and enjoy it!
I am happy to receive feedback, suggestions to improve myself.
!!! I'm sorry for the mistake if I did in this video !!!
Thank you very much for your likes, comments, and subscription!
Have a nice day

Awesome work, but just a few comments. Thats is a Deba knife, thought for fish processing. You flat grinded the urasuki. The handle is supposed to be set by burning it into the handle hole and there must be a separation between the bottom part of the blade and the upper surface of the handle that makes sharpening, cleaning and removing nasty bits that can get caught there much more easier. Cheers!

[@tizianoonaizit2994]

THANK YOU so much: I knew something was wrong with that "design editing", now I know what was it, and why.

[@johnbrooks241]

I bet this whole project started because Mr. Gear found those two little bits of epoxy and wondered what he could make with only that much... Great result!!

[@bomaite1]

Did you know that the flat side of a deba is not really flat? It is slightly concave to reduce drag on what you are cutting. You have made it more or less flat, ruining this aspect of the knife.

[@TyBraek]

I was kinda sad seeing that. The concave also helps with sharpening it means the flat side can always meet the other edge

[@wildflower1542]

Like the trick using a magnet & a sandpaper plus the water bottle with a great result ...👏💥

[@ReeseCustoms]

Is it just me, or are all of these restoration videos highly addictive?

[@bomaite1]

Deba is traditionally a fish knife. You don't need epoxy for the handle. Make the hole a little smaller than the tang and torch the tang red hot while holding the blade in the vise. Tap the handle slowly on and it will burn and seat itself very nicely. Make sure not to heat the blade, too.

[@akivameola2558]

That is a method of seating a tang, but largely a historical one. Japanese knives tend to have replaceable handles, but the burn on method is not ideal. The soot on the interior of the handle can oft act as lubrication, and will often leave an unsightly and bigger hole at the opening of the tang slot. Epoxy is typically a better standard to go by. And if you want a new handle you can still replace it easily by breaking it off. Not talking out of my ass, bladesmith with 5 years of experience here, and so far no complaints on handle design. Let the man do his thing. It's not perfect but he's going out and fixing good work.

[@karasunoendou]

That long and thick handle will be a pain in the ass when filleting a fish, which this knife was meant for and not for anymore.

[@lordofgonzo]

@@karasunoendou That's not true at all.

[@stephengardiner9867]

That was, and still is a good single bevel knife. A substantial blade, not a thin, flimsy machine stamping. Hand made by a HUMAN with a hammer and a hearth, not a machine stamping it from a sheet of steel. Despite the rust, the point is intact and there seem to be no chips from the cutting edge. Look at the thickness of the back of that blade. The shape of the tang still shows the work of the one who forged this blade. It is possible that he is long gone and your restoration of his work honors his craftmanship. He might have chosen other methods for the restoration but towards the end you employed methods that he would have recognized. I have quite an arsenal of single bevel knives and while I am not Japanese, I would not trade them for any price. Well done.

[@Gundolf300]

I'm not keen of polished knifes, but this turned out damn nice and the level of dedication regarding grinding is next level! 😉

[@dameonerichathway2298]

Well you did that the hard way! 😂 but it made it that much more worth it. 👍🏻👍🏻

[@TinyIslandMaine]

Fantastic video and excellent craftsmanship. I do have a question, on one side it seemed flat with a bevel and the other side of the blade was concave . It looks like you ground it flat on both sides. Another restoration video I recently viewed showed that the concave side was there for a reason: to help with slicing more efficiently and reducing food sticking to the blade. Is having 1 concave side common on all Japanese knives or just certain styles? Thanks 👍

[@itchy-xu2dr]

ここまで錆びた包丁を手入れして鏡面に仕上げた上で凄まじい切れ味にしたのは凄い。だけれども、裏を潰すようにヤスリがけしてしまったせいで裏すきが無くなってしまってるように見える。これでは和包丁としての機能性と特徴はなくなってしまう。それが少しだけ残念である。

[@anthonycaster9319]

Awesome job loved the magnet and sandpaper trick.

Thousands of knife making/restoring videos out there. This is a good one.

Can you please tell me where you got the heavy duty welders magnet and the two handles from ********** such a great idea in how you used them when sanding the knife bro.

[@gear_show]

Yes, it has.

Talk about an arm workout for all that sanding! That's a pretty neat magnet tool too!

[@gordbaker896]

It is a Fitup magnet for holding structural steel and pipe in place for Welding. Great use of Handles. He could polish and sharpen a Rock!

日本の伝統的な出刃包丁、海外の方が修理して使ってくれて嬉しい限りです。 日本の包丁は刃の背中部分に錆をつけて作られます。 黒錆というものがつくとそれ以上に錆が進行しなくなります。 紅茶などで黒錆を作ることができるそうなので試してみてはいかがでしょうか？

[@morriskuria6595]

Nice job.

[@patrickmorrissey2271]

Great job on this one... I honestly am surprised you got it that good... That was a mess when you started..... Maybe your next restoration should be a band saw??? Would have come in handy.....

[@PoeHxC]

Unfortunately you removed the hollow grind that this single bevel japanese knives have for a specific reason by sanding it on a flat surface. It would have been better to lock the knife and hand sand it with sand paper wrapped around a rounded element.

[@gordbaker896]

Show us how that is done.............

[@user-fj6ob2sy9q]

I have same opinion as yours. "Uraoshi" is important for this type's Japanese cooking knife.

[@yasplatcuba2592]

Just grinded the curve of the knife, that curve is to avoid food sticking to the blade, but hey, nice restoration after all.

sunflower oil or vinegar?

For rust use pool acid (muriatic acid) diluted into water, 1-3hrs all rust will be gone. You only need a small amount of acid.

Okay, thank you so much for the tips.
