This is a Toyokatsu deba knife. The blade length is approximately 16.5cm. It is a single-edged knife. The steel type is unknown. The handle is made of black buffalo horn. It has a "Tokusen" (Special Selection) stamp. I am relisting this item after making corrections, sharpening, and polishing due to some concerns with the previous listing. This is an easy-to-use deba knife. The flat and the cutting edge have been polished, resulting in a near-mirror finish. Although it has been mirror-finished, some minor scratches remain. I recommend it if you don't mind them. The black buffalo horn handle is also nice, and the overall condition is beautiful, so I think it can be used for a long time. It can be used by professionals and in general households. The whetstones used for finishing are Kitayama #8000 and Shapton #12000. It is in a very sharp condition and can be used immediately. ● Size: Blade length approximately 165mm ● Blade thickness: Approximately 6.4mm at the thickest part of the blade base ● Overall length: 305mm ● Weight: 238g #knife #deba #Toyokatsu #16.5cm #mirrorfinish
