wiki-Deba

• Definition: A traditional Japanese kitchen knife with a thick, heavy blade, primarily designed for filleting and butchering fish.
  
• Details: Deba knives typically range from 10 cm to 50 cm in blade length, with 15–20 cm being most common. They usually feature a single-bevel edge, though some regional variations use a double bevel. The spine is thick and angled near the handle, allowing leverage to cut through fish heads and bones.
  
• Comparison: Unlike thinner Japanese knives such as yanagiba or usuba, the deba is built for strength and durability. It can cut through fish bones and tougher ingredients without damaging the blade, though it is not designed for fine slicing or delicate work.
  
• Practical Use: The deba excels at filleting fish, removing heads, and breaking down whole fish. It can also be used for poultry or meat, but its primary role remains in seafood preparation. Chefs and home cooks alike value it as an essential tool for handling fish of various sizes.
  
• History: Originating in the Edo period, the deba is mentioned in texts such as the Sakai Kanjin. Its name is believed to derive from a blacksmith nicknamed “Deppa” (“protruding tooth”), whose work popularized this knife style. Over time, the name evolved into “Deba.”
