What Is a Deba Knife Used For?

A Deba knife is one of the essential traditional Japanese kitchen knives used primarily for fish preparation. Unlike a chef's knife, its thicker blade provides the strength needed for precision work while maintaining exceptional cutting performance.

The KAI AK-1100 is ideal for:

• Cleaning whole fish.

• Filleting small and medium-sized fish.

• Removing fish heads.

• Cutting through small fish bones.

• Preparing seafood for sushi and sashimi.

Although it can occasionally be used for poultry, a Deba knife is not intended for cutting large bones or frozen food.
