BLADE SHAPE:

Deba is one of the »big three« Japanese traditional kitchen knives, alongside usuba and yanagiba — essential tools for every sushi chef.

Traditionally used to prepare whole fish, the deba excels at:

• Cleaning and filleting
• Removing fins and heads
• Portioning fish
• Chopping through smaller bones
• It can also handle poultry and other meats with fine bones.

This version is a ryo-deba — a double-bevel deba — which makes it easier to sharpen and more versatile in the kitchen. Its thick and heavy blade offers both power and precision, ideal for clean cuts through flesh and bone while minimizing damage to delicate fish meat.
