The KA Series is Masamoto’s range of high-grade Ao-ko #2 (Blue Steel No.2) Japanese traditional-style knives. KA Series Kurouchi Wa Santoku is completely hand sharpened by especially skilled and experienced craftsmen, which results in extra edge sharpness and a more refined level of finish.
Masamoto KA Series knife uses a blade core of Hitachi Blue Steel No.2 (HRc. 62-63), which is forge-welded and sandwiched with soft iron. Blue No.2 steel is made by adding Chromium (0.2-0.5 %) and Tungsten / Wolfram (1.0-1.5 %) to a base of White steel No.2. This results in steel that has comparable edge sharpness to White steel No.2, but improved strength, toughness and edge retention, so it is a good choice for users who need a sharp knife throughout their working day. However, it can take a little longer to sharpen than White Steel No.2 blade.
Masamoto KA Series knife is fitted with a traditional Japanese ‘D-shaped’ magnolia wood handle with a water buffalo horn ferrule / collar.
The tall blade and rounded nose / tip of the Santoku make it a versatile knife that is well suited to cutting meat, fish, or vegetables; Hence it’s name, which literally means “Three-purpose”. The Santoku is often recommended as a multi-purpose kitchen knife.
