This extraordinary 240mm Honyaki Usuba from Genkai Masakuni (玄海正國) certainly belongs to the latter. Sharpened and finished by Nori Igarashi (五十嵐 宣), it brings together the renowned Honyaki tradition of Genkai Masakuni with the exceptional finishing skills of a highly accomplished Sakai sharpener. With its full mirror polish and beautifully flowing wavy hamon, this is a knife that deserves to be appreciated as much for its artistry as for its function.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eGenkai Masakuni is a highly respected name among Honyaki enthusiasts, particularly known for traditional Japanese differential hardening and elaborate hamon patterns. Unlike conventional laminated Japanese knives, Honyaki blades are made from a single piece of high-carbon steel, differentially hardened to produce a hard cutting edge while retaining a comparatively softer spine. The hamon is the visible transition associated with this hardening process, and its shape reflects the technique and control involved in the heat treatment. On this particular blade, the gently undulating wavy hamon runs beautifully along the length of the knife, creating an elegant contrast against the highly reflective mirror-polished surface.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe blade is made from Shirogami #2 (White 2) carbon steel, a relatively pure Japanese steel known for its ability to take an exceptionally fine edge and its pleasant sharpening characteristics. The 240mm single-bevel Usuba is designed for traditional Japanese vegetable preparation, particularly precision techniques such as katsuramuki and delicate decorative cutting. However, Honyaki construction also demands considerably more skill and care during sharpening than a conventional Kasumi Usuba. The hardened steel can be less forgiving of improper technique, while the mirror-polished surface requires careful handling to preserve its appearance.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe sharpening and finishing were entrusted to Nori Igarashi (五十嵐 宣), a highly skilled sharpener associated with Yamawaki Hamono in Sakai. Achieving a consistent single-bevel geometry on a Honyaki blade is already challenging, but bringing the entire blade to a full mirror polish while revealing the delicate hamon requires another level of patience and expertise. The result is a remarkably clean and reflective finish that allows the flowing hamon to become the centrepiece of the blade. The premium ebony set completes the presentation, offering an understated appearance that complements the knife without distracting from its craftsmanship.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFor me, the appeal of this piece goes well beyond cutting performance. A Honyaki Usuba of this calibre represents the intersection of traditional forging, highly specialised sharpening and artistic finishing, with each stage requiring skills developed over many years. The unusual 240mm length, full mirror finish and beautifully executed wavy hamon make this a particularly interesting offering for serious collectors and enthusiasts of traditional Japanese knives. It is certainly not a knife intended for casual kitchen use, but rather a fine example of the level of craftsmanship that makes Japanese Honyaki knives so highly regarded.\u003c\/span\u003e\u003c\/p\u003e","brand":"Genkai Masakuni","offers":[{"title":"Default Title","offer_id":68540140060893,"sku":null,"price":3824.98,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0287\/7227\/0217\/files\/DSC_1691.jpg?v=1794545020","url":"https:\/\/www.knivesandstones.com.au\/products\/exotic-genkai-masakuni-%e7%8e%84%e6%b5%b7%e6%ad%a3%e5%9c%8b-white-2-honyaki-full-mirror-polished-usuba-240mm-ebony-set","provider":"Knives and Stones","version":"1.0","type":"link"}
