Shiroyama Knife Workshop's Commitment

    Shiroyama Knife Workshop boasts exceptional skill and quality in knife manufacturing. We carefully select the appropriate steel for each knife and employ the optimal hardening process to maximize performance.

    For instance, Honyaki-Mizuyaki, Blue Steel #2, and White Steel #2 steels undergo water hardening, while Super Steel (Honyaki), ZDP189, and Ginsan are vacuum-hardened followed by Sub-Zero Processing. Honyaki-Mizuyaki, in particular, requires advanced techniques, resulting in exceptional sharpness.
