Fish Knives: How to Choose? The Complete Guide

Choosing a Japanese knife for fish is not something to improvise; it depends entirely on the task at hand and the delicate flesh of the product. Discover our specialized collection here.

For filleting with precision, a Japanese boning knife such as the Petty Akita knife is essential. To slice sashimi thinly without tearing the flesh, a Japanese slicing knife such as the Kiritsuke Shimoza makes all the difference.

Unlike meat, fish has a fragile structure that requires the right tool. This guide helps you distinguish rigid blades from long blades so you can work with fish with the respect it deserves.

The Different Types of Knives for Fish

Unlike the West, which often uses a single flexible knife, Japanese tradition separates each stage of fish preparation. This approach is perfectly illustrated by Maison Damas Japanese knives.

The Boning Knife: Surgical Precision

Often called a Japanese Honesuki, or sometimes confused with a small Deba knife for lighter tasks, the boning knife has a short, triangular, rigid blade.

Its role: It lets you slide along the central backbone to detach fillets with minimal waste. Its sturdy tip makes it easier to work around joints and the fish head.

The Slicing Knife (Sujihiki / Yanagiba): The Art of the Perfect Slice

Once the fillet is removed, the final cut requires a long, thin blade. In the pure tradition, a single-bevel Yanagiba would be used. At Maison Damas, the Kiritsuke Shimoza knife excels in this task with a more versatile approach.

Its role: Thanks to its length and extremely fine edge, it allows you to cut raw or cooked fish in a single motion, without a sawing effect. The result: brilliant sashimi and an intact texture.

The Chef Knife: Quiet Strength

For heavier tasks — cutting through a fish head, sectioning thick bones, or preparing a whole fish — a robust Japanese chef knife is essential.

Technical Criteria for Making the Right Choice

To buy a knife that will last a lifetime, you need to pay attention to the materials used and the ergonomics.

Flexibility vs. Rigidity: A Clash of Cultures

In Europe, people often favor the flexibility of a thin blade to follow the backbone of a sole. In Japan, blade rigidity is preferred for better control.
