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.

Size

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. 

Flex

Fillet knives have semi-hard blades, which means they are made to be flexible. However, that also means that they aren't that sturdy either. 

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

Blade Construction

High carbon stainless steel blades are preferable. Not only will they be more durable, but they will also have better edge retention and are able to retain their sharpness for a long time. 

If you want the best knife for filleting fish, you should choose a knife that has a blade made from high-carbon stainless steel. 

Handle

The blade isn't the only important part of a knife. You should also pay attention to the handle design. The ideal fillet knife should have a good ergonomic handle with a solid grip.

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.
