This is a Yushige yanagiba knife. The blade length is approximately 23.5cm. It is a single-edged knife. The steel type is unknown. The handle is a buffalo horn handle. The cutting edge was thin and sharpened like a fugu (pufferfish) knife, so I followed suit and re-sharpened it. The knife had been sharpened with a raised shinogi (ridge), so I slightly corrected the blade line, but I gave up on drastically changing the shape because it would have significantly reduced the steel of the blade (steel is the priority). I corrected most of the rust marks, but some small scratches remain because I mirror-polished it. I recommend it if you don't mind. It is in overall beautiful condition, so I think it can be used for a long time. It's a good size, so don't miss out. The flat and cutting edge are almost mirror-polished. It is lightweight and a good size, so I recommend it for both professionals and general households. The whetstones used for finishing are Kitayama 8000 grit and Shapton 12000 grit. ● Size: Blade length approx. 235mm ● Thickness at the thickest point: approx. 3mm ● Overall length: 390mm ● Weight: 111g #knife #yanagiba #Yushige #23.5cm
