The KURO series is a heavy ironclad knife that feels substantial in the hand while the walnut handle is smooth and warm. The White #2 Carbon edge with soft black iron cladding provides a distinctive look as the final layer of iron has an oxide coating to help prevent rust. Heavy and solid, these knives are heavy duty workhorses. Hand engraved with the Kikuichi chrysanthemum logo. Blade: 3 Layers; Hand Forged. Edge: White #2 Carbon Steel. Layers: Iron with Oxide Coating. HRC: 62. Bevel: Double. Bevel Angle Ratio: 50:50. Handle: Octagonal Wa Handle, Walnut handle. CAUTION: All Carbon steel blades will patina through regular use and may rust if left wet.

This is NOT stainless steel. – KURO18 – 0 – B116-2
