This is a Yanagiba knife from Masamoto Sohonten. The blade length is approximately 23cm. The steel type is unknown (probably Shirogami - white steel). The handle is made of black water buffalo horn. It is a single-edged knife. There were rust and scratches, but most have been corrected. However, a slight pitting mark remains on the cutting edge near the base of the blade. Other than that, almost all scratches and rust have been removed, and it is clean. I recommend it if you don't mind the pitting. The flat and cutting edge have been polished, resulting in a near-mirror finish. It is generally clean, so I think it can be used for a long time. With a blade length of 23cm, it's an easy-to-use size, recommended for both professionals and home cooks. The knife has been finished with a Kitayama 8000 grit and a Shapton 12000 grit whetstone. It is in a very sharp condition and can be used immediately. ● Size: Blade length approx. 230mm ● Blade thickness: Approx. 3.2mm at the thickest part of the base of the blade ● Overall length: 380mm ● Weight: 118g #Knife #Yanagiba #Masamoto #23cm #MirrorFinish
