The Shigemitsu Hamono Kurouchi Thin Deba Knife 155mm is a handcrafted Japanese fish knife forged in Shimabara, Nagasaki, by the Inoue family at Shigemitsu Hamono. Led by third-generation blacksmith Hiroyuki Inoue and his son Yuuki, the forge continues over a century of hands-on craftsmanship. Built for real kitchen work, this kurouchi-finished Deba is shaped, hardened, and sharpened entirely by hand to deliver strength, control, and clean cuts while preserving the texture and flavor of fish. About the Blade Shape: A traditional Japanese fish butchery knife, deba knives are built for breaking down whole fish with power and control. The thick spine and substantial weight provide strength for cutting through heads and bones, while the sharp double-bevel edge allows for precise filleting work. Although traditionally designed for fish preparation, they are also suitable for cutting poultry and other meats with small bones as well. Your Shigemitsu Hamono knife comes lightly coated with camellia oil to prevent rust. This may cause the blade to feel sticky, but is harmless and helps keep your knife from rusting. We recommend re-applying a light coat of camellia or other food-safe knife care oil before long-term storage.
