Yanagiba knife, blade length 19.9cm, 117g. The spine is about 3.5mm thick near the top of the heel. It seems to be a brand from a while back. I can only find it on the used market. It's a genuine kasumi blade, made by layering soft iron and steel. Although it showed little use, it had some rust, so I polished it, and I think it's mostly gone and looks clean now. About 70% of the plastic handle's luster remains. It seems like it can still be used for a long time. I sharpened it well, put an edge on it, and polished it. Please see my profile for detailed restoration processes.
