Deba, Yanagiba & Sujihiki: Japanese Fish and Slicing Knives
Sep 27, 2026
Deba, yanagiba and sujihiki are three specialist Japanese knife styles built for different stages of fish and protein preparation. The deba is for breaking down whole fish, the yanagiba for long precise slices, and the sujihiki for double-bevel slicing of boneless proteins.
Deba: whole-fish breakdown
A traditional deba is thick, heavy and usually single bevel. It is used to remove heads, fillet fish and work through appropriate fish bones with controlled pressure. It is not a cleaver for large animal bones.
Yanagiba: precise fish slicing
A yanagiba is long, narrow and traditionally single bevel. Its length allows sashimi and sushi toppings to be cut with one smooth drawing stroke, reducing the need for sawing motions.
Sujihiki: double-bevel slicer
A sujihiki is a long, narrow slicing knife, generally double bevel. It is useful for boneless fish fillets, roasts, ham and poultry breast, and is easier to use ambidextrously than a traditional single-bevel slicer.
Which is most versatile?
Sujihiki is the easiest of the three to integrate into a general Western-style kitchen. Deba and yanagiba are more specialised and reward correct technique.
Which one is for raw fish?
Yanagiba is the traditional choice for clean sashimi slices. Sujihiki can also slice raw boneless fish effectively, especially for cooks who prefer a double-bevel knife.
Which one handles whole fish?
Deba is the specialist for breaking down whole fish. Yanagiba and sujihiki are slicers and should not be used for heavy bone work.
Maintenance
Traditional single-bevel knives require different sharpening technique from double-bevel knives. Always confirm the bevel construction before sharpening.
