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!
