What is the best knife size you should opt for?

The size depends on the fish size you expect to fillet.

Small blades are suitable for small-sized fish and vice versa.

Nonetheless, a medium-size knife of 7 inches is a good pick for a one-size-fits-all.

What material should you choose?

Stainless steel is ideal for the blade and a non-slip surface for the handle.

So, make sure you pick up one that fits these criteria.

And now, for the most wanted part.

How to Choose One?

Before heading out to buy something, there are a few factors to consider.

The Blade

This is probably the most vital part. The reason being, it is the one to determine how clean your cuts will be.

Also, keep in mind it may be subject to wet environments. Saltwater, in particular, may corrode the blade hence affecting its performance.

With this in mind, you should consider a blade that is corrosion and rust-resistant.

Handle Grip and Comfort

Having a fillet knife with a comfortable and non-slip handle makes the filleting process quicker and easier.

Also, sometimes you may have to use it with wet hands. So, a non-slip grip handle is essential for better control.

Size

The size factor narrows down to the type of fish you will be filleting. Different knife blades come in varying lengths. And, each length is best suitable for a particular size and type of fish.

In other words, shorter blades are best when you need high-precision cuts. They are also convenient when using on small-sized fish like crappie.

Medium-sized blades, roughly around 7 inches, are perfect for filleting fish like bass or trout.

Larger blades, on the other hand, are best to use on larger fish. At the same time, it’s size matters when you think of transportation and storage options.

If you have less space, consider smaller or folding options.

Strength

Fillet knives are available in varying blade thickness levels. In simple terms, a thin blade means a flexible knife. Such knives are handy for removing bones and using them on small-sized fish.

However, they may not be best for filleting sizeable fish. It may be a result of too much flexibility and less strength.
