What blade size is the best?

A 7.5-inch blade might be the best choice.

The length is great for small and medium-size fish.

Since most catches fall into this category, a 7.5-inch-long blade will do.

Should it be flexible?

Yes, your blade should be flexible.

A flexible blade will easily follow your hand movements.

As a result, you will excellently remove the skin from fillets.

So now, let’s take a look at my personal favorite list when it comes to the most budget-friendly fillet knives under $50.

Buying Guide

Material

The first factor you want to consider is its material.

Stainless steel is the standard material for your knife‘s blade.

But stainless steel comes in varying qualities.

Be sure to look for knives with high-carbon stainless steel if you want your blade to retain its sharpness for long and stay rust-free.

Size

The next step would be to check for size.

Fish come in various sizes.

A larger fish will demand longer blades, while a smaller fish will need a shorter blade.

You can be sure to get blades ranging from 4 inches to 9 inches.

You know the fish sizes you usually handle.

Be sure to arm yourself with the right blade length.

The Handle

First, the handle should be ergonomic and non-slip.

Such a handle will ensure you have the best grip for more control of it.

Besides, you will need a comfortable grip to fillet your fish into the right sizes for cooking.

You can also check the material quality.

Rubber handles are more durable and have an excellent non-slip grip.

Also, make sure the weight on this side is light for more control and arm movement.

Sharpness

Sharpness is another important factor to consider.

Your knife should be ultra-sharp for better performance.

Also, a razor-sharp knife will perform at its best when filleting a fish.

You could also buy a knife that includes a sharpener so that you can always hone it whenever sharpness reduces.
