This is a Masanaga Betsusaku Takohiki knife (sashimi knife). The blade length is approximately 19.5cm. It has the "Saiko" (highest quality) stamp. It is a single-edged knife. The steel type is unknown. The handle is made of black buffalo horn. I have corrected some points from the previous listing. I have mirror-polished the blade, so some minor scratches remain, but I recommend it to those who don't mind. It's an old knife, but I've sharpened it, so it has a good sharpness. It is in overall clean condition, so I think it can be used for a long time. I think it's an easy-to-use size that can be used by professionals and in general households. The cutting edge is also almost mirror-polished. It has been finished with Kitayama 8000 grit and Shapton 12000 grit whetstones. It is in a very sharp condition, so it can be used immediately. ● Size: Blade length approx. 195mm ● Blade thickness: Approx. 4.3mm at the thickest part of the base of the blade ● Overall length: 355mm ● Weight: 163g #Knife #Takohiki #MasanagaBetsusaku #19.5cm #Mirrorfinish
