Choosing the Best Fillet Knives | A Definitive Buyer's Guide

Choosing the best fish fillet knife isn't that hard. If you already own kitchen knives, you will probably know the basics of choosing one. 

However, since filleting knives, in general, are slim, long, and flexible, there are some features you should look for before buying one.


The first thing you should look for is the size. Choose a blade depending on how large the fish you usually fillet. 

Most probably a 7-inch blade will be more than enough. If you want more precise control when cutting smaller fish, go with smaller knives.

There is a good balance between flexibility and durability, and only the top-tier knife manufacturers know how to maintain that sweet spot.

Since you will be filleting fish most of the time, your hands are bound to get wet and slimy. Having a good no-slip traction grip is crucial if you want proper control of your knife. 

The handle design should be comfortable. Preferably a bolster-less or seamless handle will give you a good amount of comfort and control.
