Based in the Aomori prefecture of Northern Japan, Nigara Hamono is renowned for its exceptional cutlery and tools, backed by centuries of experience in metalwork—from forging blades to producing steel beams for buildings. The Nigara Aogami Super Migaki Tsuchime Kiritsuke Sujihiki 255mm features a unilaterally polished (migaki) finish and a distinctive tsuchime (hammered) pattern, delivering a striking visual of layered grays. Its Aogami Super carbon steel core ensures top-tier edge retention and cutting performance.\nFor maximum sharpness straight out of the box, add our Professional Sharpening Service. This sujihiki—designed primarily for slicing proteins—pairs perfectly with a Hasegawa Cutting Board to help maintain its edge for up to a year between sharpening sessions.\nCommon Questions\nQ: Is this knife suitable for home cooks?\nA: Absolutely. While often favored by professionals for precise slicing of meats and fish, the sujihiki’s long, slender blade also benefits home cooks who want clean, effortless cuts.\nQ: How should I care for Aogami Super steel?\nA: Aogami Super is a high-carbon steel, so dry it thoroughly after each use to prevent corrosion. Occasional use of a light coat of food-safe oil on the blade can also help guard against rust.\nSpecifications\n\n\nBlacksmith: Nigara Hamono\n\nLocation: Hirosaki, Aomori, Japan\n\nShape: Kiritsuke Sujihiki\n\nConstruction: San Mai (laminated)\n\nCore Steel: Aogami Super (Blue Super)\n\nCladding Type: Stainless Steel\n\nFinish: Migaki Tsuchime\n\nBlade Length: 240mm (255mm is Sakai measurement from tip to machi)\n\nSpine Thickness (Heel): 2.1mm\n\nSpine Thickness (Mid): 2.1mm\n\nBlade Height: 38mm\n\n\nWeight: 163g\n\nHandle Material: Ebony with Buffalo Horn Ferrule\n\nHardness (HRC): 63-64\n","images":["https://cdn.shopify.com/s/files/1/0602/6720/0736/files/NigaraASSujihiki255mm.jpg?v=1780759122","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/NigaraASSujihiki255mmUpsidedown.jpg?v=1780759122","https://cdn.shopify.com/s/files/1/0602/6720/0736/files/NigaraASSujihikiChoilShot.jpg?v=1780759122"],"price":269,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:30.635Z"},"share_url":"https://firestarter.network/l/lst_fHUIf5Nt","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
