Petty – Compact Precision

The petty knife is the Japanese equivalent of a paring or utility knife. Small, nimble, and extremely versatile, it’s perfect for tasks that require precision — from peeling fruit and trimming herbs to preparing garnishes and working with smaller cuts of meat. A petty makes the ideal partner to a larger gyuto or santoku.

San Mai – Three-Layer Construction
San mai means “three layers.” It describes the traditional Japanese method of sandwiching a hard steel core between two softer layers of protective cladding. The hard core provides razor-sharp cutting performance, while the outer layers add toughness and make the knife easier to maintain.

Steel Care
• Always hand wash immediately after use — never in the dishwasher.
• Dry completely with a towel to prevent rust or discolouration.
• Use wooden or soft plastic cutting boards to preserve the edge.
• Store safely — in a knife block, magnetic rack, or saya cover.
• Sharpen regularly using whetstones for best long-term performance.
• Carbon steels will form a patina over time — this is normal and protective.
