Japanese Ko-Bunka 100% Homemade | DIY

Making a japanese chef's cutting tool starting from raw materials with many of the tecniques I have shown in previous videos like stabilizing wood and making liners from scratch.
The materials are:
2mm thick Nitro B Stainless steel for the blade, mild stainless steel for the guard and a stack of felt and paper liners, stabilized cork and stabilized elm wood for the handle.
With this build I wanted to try a half mirror half satin finish on the blade. I tought it would have looked cool but it looks a bit more like a not fully finished blade. This is a gift to my uncle by the way so I can always change my mind later and make it full mirror or (much easier) full satin. You never try, you never know!
Here are some of the videos where I go in more details about some of the tecniques used in this video:

Good job my friend

[@WastedFrom1976]

Video's like this really benefit from a text/verbal commentary at key moments to give a short explanation of the whys and wherefores. It's still entertaining, just a bit numb to stop the video and research what went on before continuing.

[@JKinsman92]

What kind of tomato was that, it looks great. Beautiful knife, as always.

[@bbowling4979]

Beautiful work my friend! I really like the stacked handle.

[@MMitchellMarmel]

Simple but elegant. Your uncle is a fortunate man.

[@jimmyeatshoe]

Stunning! Love seeing the bench tools that you have restored getting good use. The collection is growing! 💪⚒️

[@jasonweninger]

It's the little things you do, the extra details you put in these, I think are the reason I watch every one. Awesome job!

[@PaskMakes]

It's a beauty mate! You show so many processes that I need to try out! :)

[@paulsimmons5726]

The cutting demonstration at the end said it all. Excellent work!

[@kenziethekorean4509]

By far the most beautiful knife I’ve ever seen. I’ve binge watched every video multiple times lol. Such an amazing person. Love how he never wastes materials unlike other youtubers.

[@karikovacs3824]

Restorations, building them up from zero and filming it like a pro, man you give me back my hope for mankind! Thank you.

[@e.t.preppin7084]

Have to say WOW. Looks gorgeous. Have to watch later!!!

[@timberdish]

Very tasteful looking knife in what was a stunning build, as always. Thanks bro, always a pleasure to watch.

[@leebumble]

This channel is great, no unnecessary chatter, no pulling silly faces and telling stupid jokes, no bippity-boppity dance music and other unnecessaries that distract from the make. The focus should be on the creation and personality expressed through the piece IMHO. Yet another MASTERPIECE btw 👍👍👍

[@Marq91F]

I am speechless, its so incredibly beautiful!

U really a Handwork Fox . So professional. 👏👏👏👏👏🏆

[@Madlintelf]

Amazing as usual but I think it's time you start putting a makers mark on your work, it's so beautiful and people need to recognize your skill! Great job, looks fantastic, love your technique with the tang and dowel for the handle!

[@TweedleDurp]

Beautiful knife! For stabilizing, after you release vacuum, you should let the wood soak for a while longer. most of the resin is absorbed after the vacuum is released, while the voids in the wood try to refill.

[@YooProjects]

Amazing job! Thanks.

[@sonyhk3824]

Well done it's awesome

That was amazing mate, it's just a piece of art you just made, the only thing I wanna see is to make your blade out of the forge not just cutting a piece of metal, thx for the great work again

[@brose04008]

Love your work. Need to see a vid where you work with some of the really insane tool steels-K390 would be awesome! Keep up the good work in any case.
