Preparing fish properly requires precision, control and, above all, the right knife. A fillet knife is specifically designed to separate the flesh from the bones, remove the skin and lift clean, even fillets while limiting waste. Whether you regularly prepare salmon, sea bass, trout, sole or other fresh fish, a good fish filleting knife can make a huge difference.
Unlike a chef's knife, a fish fillet knife generally features a long, narrow blade with a certain degree of flexibility. This flexible blade follows the natural contours of the fish and slides close to the bones, allowing you to recover as much flesh as possible. The pointed tip is also useful for making precise incisions and working around delicate areas.
There are many different types of fillet knives. Some have very flexible blades, ideal for delicate fish such as sole, while others are slightly firmer and better suited to larger fish. Blade length, steel hardness, handle ergonomics and ease of maintenance are also important criteria. Professional fishmongers may prefer a highly hygienic, non-slip professional fillet knife, while home cooks may focus more on versatility, comfort or cutting performance.
From Japanese craftsmanship to professional European knives, we have selected 10 of the best fillet knives for fish available on KnifeLeader. There is something here for every budget and every type of use!
1. Glestain Home Series Japanese Fillet Knife 18cm
The Glestain Home Series 18cm fillet knife offers a particularly original Japanese approach to fish preparation. Made in Niigata Prefecture, Japan, its 18cm blade is manufactured from ACUTO440 stainless steel and reaches approximately 59 HRC. A Sub Zero hardening process improves the steel's strength and durability while helping the blade retain a very efficient cutting edge.
One of the most distinctive features of this Japanese fish knife is its honeycomb surface. These hollowed areas reduce the contact between food and the blade and help prevent slices of fish from sticking during cutting. The convex cutting edge also provides smooth penetration into the flesh for clean and controlled cuts.
Its stainless steel Western-style handle gives the knife a modern appearance while providing excellent balance and a secure grip. Compared with extremely flexible professional fillet knives, this model is particularly interesting for cooks who prefer a more precise and controlled Japanese-style cutting sensation.
Its number-one selling point: exceptional Japanese cutting performance combined with Glestain's characteristic non-stick honeycomb blade.

Which fillet knife should you choose?
The best fillet knife depends mainly on how often you prepare fish, the type of fish you usually work with and your budget. There is no need to choose the most expensive knife if you only fillet a few fish occasionally. A simple, flexible stainless steel blade with a comfortable handle can already provide excellent results.
For occasional home use, models such as the 32 Dumas Thermo Black or Sabatier Trompette Vulcano offer an excellent balance between price, flexibility and ease of use. If you prepare fish regularly and want superior steel or a more refined finish, the Fischer SANDVIK models, Wüsthof Classic Ikon or Japanese Glestain are worth considering.
Professionals should pay particular attention to the handle, hygiene and ease of sharpening. Fishmongers and restaurant professionals may use their fillet knife for several hours a day, so a non-slip handle and a steel that can be quickly resharpened are particularly important. This is where models such as the Victorinox SWIBO, Giesser or Sanelli Premana really stand out.
Blade length is another important consideration. A 16 to 18cm fillet knife provides excellent precision and is suitable for most common fish, while a 19 or 20cm fish knife gives you more reach for larger specimens. Finally, consider blade flexibility: a highly flexible blade is ideal for delicate filleting and removing skin, while a slightly firmer blade provides greater control for thicker or larger fish.
Whatever model you choose, a dedicated fish filleting knife will make preparing fresh fish faster, cleaner and more precise. Once you have experienced how easily a thin flexible blade follows the bones and separates the flesh, it quickly becomes an essential knife for any fish lover!
