Sujihiki is the dedicated slicing knife of the Japanese kitchen, built long and narrow for clean cuts through proteins without the sawing motion a shorter blade would require. Hatsukokoro builds this 270mm version around Aogami Super, a Hitachi carbon steel known for taking and holding a very steep, sharp edge.
The blade is roll forged in a san mai construction, with the AS core clad in stainless steel and brought up to a bright migaki, or polished, finish. Roll forging uses steel already flattened to a consistent thickness, so the blade is stamped directly to shape rather than hammered out from a rough billet. Hardened to 62-63 HRC, this steel sharpens easier than its hardness might suggest, and the even edge grind works for both right and left handed cooks. A single piece octagonal ebony handle with a stained, lacquer coated finish rounds out a knife built for serious slicing work.
Care Instructions: Aogami Super is a reactive carbon steel and one of the hardest available, so it rewards good sharpening technique and stropping between uses. Wipe and dry the blade immediately after use, avoid leaving acidic foods against it, and apply a light coat of camellia oil for longer term storage. Hand wash only.
