All-purpose knife, blade length 16.8cm, 125g. The back is about 1.9mm thick near the top of the heel. I believe it's a brand from Hidetetsu, a knife shop in Edogawa-ku. It's a warikomi (laminated) knife, but the sandwiched steel is probably stainless steel, though I'm not certain. It shows very little use, and both the blade and handle are clean. It doesn't feel heavy, and the handle is plastic, so the original price probably wasn't very high, and it's likely a mass-produced type, but it seems perfectly usable as a warikomi knife. It should last for quite a while. I sharpened it thoroughly, put an edge on it, and polished it. Please see my profile for detailed restoration processes.
