Heritage

Katsuhiro knives are famous for high-frequency induction thermal hardening - a process that uses localized electrical currents to rapidly heat and quench only the cutting edge, achieving extreme hardness while keeping the spine resilient and flexible. This mirrors the differential heat-treatment of a traditional Japanese katana. The distinctive wavy clad line where soft outer iron meets the hard carbon steel core is a hallmark of this steel, and the 登録 (Tōroku) registered stamp confirms authenticity. The lightweight magnolia handle keeps the balance tip-forward for effortless vegetable and protein work.

• Dry immediately after use to prevent oxidation
