Matsubara Kurouchi Shirogami #1 Petty 150mm
This Petty was forged in traditional handwork by Tanaka-san from the Matsubara forge in Japan. The utility knife is ground on both sides and has a matte Kurouchi surface. Kurouchi is a special type of surface finish that is not atypical on Japanese knives. The surface is carbonized and therefore black. This blade finish significantly improves the resistance and corrosion resistance of the knife, in addition to creating this rustic aesthetic.The core of the blade is made of White #1 steel. White #1, or Shirogami 1, is a steel made by Hitachi and is extremely popular with Japanese chef's knives, as it brings ideal properties for a sharp blade. The steel (Japanese: Hagane) can be brought to over 65 HRC depending on the hardening process, which allows the blade to be ground very sharp. A layer of softer carbon steel is welded around the blade core using the San Mai method. The softer carbon steel on the blade blade not only protects the inner steel core, but also gives the blade a degree of flexibility.
