Fish Knives: How to Choose One? 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.

To fillet with precision, a Japanese boning knife such as the Honesuki Akita knife is indispensable. To slice sashimi finely 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 a suitable tool. This guide helps you distinguish rigid blades from long blades so you can work the fish with the respect it deserves.

The Different Types of Fish Knives

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

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 allows you to slide along the backbone to lift the fillets with no loss. Its sturdy tip makes it easy to work around joints and the fish head.

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

Once the fillet is lifted, 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 cuts raw or cooked fish in a single motion, without a sawing effect. The result: glossy sashimi and an intact texture.

The Chef Knife: Quiet Strength

For heavier tasks — cutting through a fish head, severing thick bones, or preparing a whole fish — a sturdy Japanese chef knife is indispensable.

Technical Criteria for Choosing Well

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

Flexibility vs. Rigidity: The 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 sought for better control.

A rigid blade, typical of Japanese knives Maison Damas, offers precise tactile feedback, allowing you to feel the backbone exactly beneath the steel.

Corrosion resistance and materials

Fish is a wet and demanding environment. Knives with a VG10 steel core offer an excellent balance of performance and durability.

• Stainless steel: Essential for preventing rust caused by moisture and salt.
• High carbon content: Guarantees razor-sharp edge retention, but requires more maintenance.
• Damascus steel: Protects the carbon core with stainless steel layers.

Ergonomics and handle

Grip is crucial when hands are wet or covered in scales. A treated wood or G10 handle must be water-resistant and non-slip.

The versatile option to get started

If you cook fish occasionally, a Japanese Santoku such as the Santoku Sakoma may be enough. Versatile and balanced, it is well suited to fish fillets and simple cuts.
