Factors to Consider When Selecting for the Fish Fillet Knife

A horrible fish fillet knife may be all it takes for you to swear never to go fishing again. Therefore, if you want to end up with a product that is worth your money, there are several vital aspects that you have to look out for.

Let’s check them out.

The Blade

We can confidently say that this is the most vital part of any knife, and for the fish fillet knives, there are several properties of the blade that you need to consider.

The material

The ideal material for the blade should be sturdy, durable, and easy to sharpen. On top of that, it should be easy to clean to make it easy to keep it in good shape.

Excellent examples of high quality blade materials include stainless steel, titanium steel, and high carbon steel.


An extremely sharp edge would give you the ability to make precise cuts through the fish. Further, ensure that the blade can retain its edge for longer without blunting.

The size

When dealing with smaller fish, you are best suited to work with shorter blades measuring around five inches. For the average-sized fish, a length of roughly seven inches would be ideal.

As for the larger fish, blades of at least 8-inches would give the best performance.


In most cases, thicker blades are stronger than the thinner competitors and would slice through fish, even the large ones, more efficiently.

The Handle

This is what determines the level of control that you would have with your knife. The material used in its construction should be the one that ensures you do not get easily fatigued even on long durations of use.

The best handles for fillet knives are made of wood, plastic, or rubber.

What’s more, is that the handle should have a strong and firm grip so that it does not slip out of your hands easily.


A flexible knife is one whose knife can bend to offer you more precision. This is more useful when filleting the smaller fish. Further, you should find the thinner and smaller blades to be more flexible than the thicker ones.

Electric or Non-Electric knife

Although the electric fillet knives allow you to work on more fish, the non-electric knives tend to offer more control and precision as you fillet your fish.

If you are filleting for commercial purposes, we advise that you go for the electric fillet knife.


The process of filleting fish can be a messy affair involving lots of blood and slippery surfaces. Therefore, it would be wise if you get a fillet knife with safety features.

For instance, a dimpled handle would give you a firmer grip and more stability. Some knives also feature finger guards at the point where the blade and the handle meet.
