This is a Masahana Takobiki knife (sashimi knife). The blade length is approximately 33cm. It is single-edged. The steel is unknown, but it is probably Shirogami (white steel). The handle is made of black water buffalo horn. The shinogi (ridge) was slightly raised, so the shinogi line was not corrected. There were rust and scratches, but most of them have been corrected, so it is in a clean condition. The blade is thin, so there were many small chips. Most of them have been removed and corrected to a level that does not affect the sharpness, but they are barely noticeable and will likely disappear with use. It has been mirror-polished, so some fine scratches remain, but I recommend it if you don't mind. It is old, but it has been sharpened, so the sharpness is good. It feels like a razor. This is a 1-shaku 1-sun Takobiki, so I recommend it to professionals or those confident in their skills. The whetstones used were Kitayama 8000 grit and Shapton 12000 grit for finishing. It is in a very sharp condition and can be used immediately. ● Size: Blade length approx. 330mm ● Blade thickness: Approx. 3.4mm at the thickest part of the blade base ● Overall length: 490mm ● Weight: 118g #knife #takobiki #Masahana #33cm #mirrorfinish
