Its nimble size is ideal for trimming proteins, peeling fruit, slicing garlic, preparing herbs, deveining shrimp and working around smaller ingredients where a full-size gyuto feels oversized.\u003c\/p\u003e\n\u003cp\u003eThe Kokusen line pairs an Aogami Super (Blue Super) carbon-steel core with stainless cladding and Yu Kurosaki’s distinctive hammered finish. The hard core takes a keen edge and holds it well, while the stainless cladding reduces maintenance across most of the blade.\u003c\/p\u003e\n\u003cp\u003eChoose between an octagonal rosewood wa handle with a black pakkawood ferrule or an octagonal ebony wa handle with a buffalo horn ferrule. Both options keep the knife light, balanced and comfortable for detailed prep.\u003c\/p\u003e\n\u003cp\u003eThe exposed carbon-steel edge is reactive and will develop a natural patina. Hand wash only, wipe dry promptly during use and never place the knife in a dishwasher. Avoid bones, frozen foods and twisting cuts.\u003c\/p\u003e\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e What is a 120mm petty knife best used for?\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e A 120mm petty is ideal for small, controlled cutting tasks such as peeling, trimming, slicing fruit, mincing garlic, preparing garnishes and working in tight spaces on the cutting board.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ:\u003c\/strong\u003e Is the blade fully stainless?\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. The cladding is stainless, but the exposed Aogami Super core at the cutting edge is carbon steel.
