Our Gohumanosuke Yoshihiro Mizu VG-1 Petty knife covers tasks from fine garnishing to utility purposes with ease and agility. Mizu, the Japanese word for water, refers here to the process of hardening the steel by quenching it in cold water. Next, the steel is put through different phases of tempering for strength. The Yoshihiro Mizu series uses VG-1 stainless steel which easily achieves a razor sharp edge that holds for an extended period of time. Yoshihiro bladesmiths add Molybdenum for hardness, toughness, corrosion resistance and a high tensile strength. Vanadium is added for strength, toughness and heat resistance. Moreover, Vanadium promotes a desired fine grain structure which allows for even wear resistance. These blades are single piece forged with a Burned (Kokutan) Japanese Oak octagon handle.
