{"type":"firestarter.listing","listing":{"id":"lst_z3w7c34g","product_name":"Nigara Hamono SG2 Migaki Tsuchime Gyuto 240 mm Abalone Western Handle","category":"Gyuto Knife","description":"Overview\nForged in Aomori by Nigara Hamono, this 240 mm Gyuto pairs a razor-hard SG2 powder-steel core with rugged kurouchi tsuchime stainless cladding for striking good looks and fuss-free care. The long, gently curved edge glides through everything from sweet potatoes to sous-vide striploin, while the full-tang Western handle—dressed in shimmering abalone-resin scales and anchored by a nickel-silver bolster—adds confident balance and serious wow factor on the prep line.\nCommon Questions\nQ: Is the listed 240 mm the sharpened edge length?A: Nigara measures from the neck (machi) to the tip. The true cutting edge is about 228 mm, giving you generous push-cutting real estate without feeling oversized.\nQ: How often will I need to sharpen SG2?A: Thanks to its 62-63 HRC hardness, SG2 holds an edge for months of typical home use. A quick leather strop refreshes the bite; full stone work is only needed a few times a year.\nQ: Will the abalone handle survive daily kitchen abuse?A: The resin-stabilized abalone shell is waterproof and dimensionally stable—wash gently, dry promptly, and it will sparkle for decades.\nSpecifications\n\n\nCore Steel: SG2 powder stainless steel\n\nCladding Type: Stainless steel, tsuchime finish\n\nBlade Length (listed): 240 mm\n\nActual Edge Length: 228 mm\n\nSpine Thickness (Heel): 2.3 mm\n\nSpine Thickness (Mid): 2.1 mm\n\nSpine Thickness (1 cm from Tip): 0.8 mm\n\nBlade Height (Heel): 51 mm\n\nOverall Length: 380 mm\n\nWeight: ~290 g\n\nHandle Material: Abalone-resin scales, nickel-silver bolster (Western full-tang)\n\nHardness (HRC): 62 – 63\n","images":["https://cdn.shopify.com/s/files/1/0602/6720/0736/files/nigara-sg2-tsuchime-gyuto-240mm-abalone-western-handle-03.jpg?v=1781437120","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/nigara-sg2-tsuchime-gyuto-240mm-abalone-western-handle-01.jpg?v=1781437120","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/nigara-sg2-tsuchime-gyuto-240mm-abalone-western-handle-02.jpg?v=1781437120","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/nigara-sg2-tsuchime-gyuto-240mm-abalone-western-handle-04.jpg?v=1781437119","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/nigara-sg2-tsuchime-gyuto-240mm-abalone-western-handle-05.jpg?v=1781437120","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/nigara-sg2-tsuchime-gyuto-240mm-abalone-western-handle-06.jpg?v=1781437120"],"price":599,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:30.148Z"},"share_url":"https://firestarter.network/l/lst_z3w7c34g","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
