Care

Aogami #2 and the soft-iron cladding are reactive. Hand-wash and dry the knife immediately after use, expect a patina to develop, and avoid bones, frozen food, twisting, or prying. Use wood, quality soft plastic, or rubberized cutting boards. Single-bevel geometry also requires the correct handedness and a different sharpening approach from a double-bevel gyuto.
