General-purpose knife, blade length 16.0cm, 144g. The spine is about 3.0mm thick near the top of the heel. It's a brand called Sumida River, and while it comes in fairly often, it seems to be an older brand. You can only find it in the used market. It's a brand known for Japanese knives, but this is unusually a general-purpose knife. It's a Hon-Warikomi knife, but the sandwiched steel is not stainless steel. You need to be careful about rust on the blade tip. It's a very heavy general-purpose knife. The handle doesn't show much wear and tear and seems like it will 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.
