Deba knife, blade length 15.5cm, 138g. The spine is about 2.9mm thick near the top of the heel. It's engraved with "Tetsuro" and is a brand of Kiryu Kogyo Co., Ltd. in Sanjo City, Niigata Prefecture. It's a brand that's fairly often in stock. It's all-steel stainless steel, but it doesn't have much thickness or weight, and the original price seems to have been low. It has a decent hardness, typical of modern stainless steel. The front side has a unique and beautiful pattern that's not often seen. The plastic handle retains about 70% of its luster. It seems like it will be usable for quite a while. I sharpened it thoroughly, put an edge on it, and polished it. Please see the profile for detailed restoration processes.
