Just started to get into kamisori, and decided while on zombie apocalypse isolation, I would buy a fixer upper and spend some time making her work. I have done this successfully on several western blades, so this was going to be my first kamisori.

I bought an old Asanuma tamahagane. If I am going to do it, might as well do it right... right? Looking at the ebay photos, I thought most of what I was seeing was surface gunk, and not bad pitting near the edge. Well... getting it in hand, I spent 10 mins with 200 grit sandpaper, and about 20 mins with MAAS... to find I was wrong:

This is the toe.

Win some, you loose some, I guess.

I may put an edge on it where it will take one, and make it a traditional Japanese box cutter.
