Deba knife, blade length 15.2cm, 218g. The back is about 7.9mm thick near the top of the heel. Unfortunately, the maker's mark is gone. This is a genuine kasumi (layered steel) knife made by forging soft iron and steel together. I think the rust marks are mostly removed and it's become clean. If you look closely, there are some faint marks remaining, so please check the photos carefully. The handle has been replaced with a new one and should last for a while. I sharpened it thoroughly, put an edge on it, and polished it. Please see my profile for the detailed restoration process.
