Additional Information: Unused, in good condition. I sharpened the chisel blade bevel and "ura" side to 400 grit and 5000 grit respectively. If you need to use it, you need to continue sharpening the blade bevel.

I found it in a display case at a specialty tool store in Tokyo. Although it uses a wholesaler postmark, I was impressed by the high quality of the blade and wooden handle (including the metal attachments). The sides and top of the blade are concave；the rings and “kuchigane” are hand-forged.
