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


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.


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 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.

Are there pocket-size fillet knives?

Yes, there are plenty of smaller fillet knives that are ideal for camping or outdoor activities while out in the wild.

Can I use a dishwasher to clean my knife?

You could, but that might be inappropriate.

The dishwasher may dull the razor-sharp cutting edge.

As such, be sure to handwash the knife.

Can I use my fillet knife for boning?

Yes, you can use it to bone turkey or fish.

How long does it stay sharp?

It depends on the frequency of usage.

Your blade will become dull sooner if you use your knife a lot.

After 4-5 uses, it may lose its impressive sharpness, and you will need to hone it to restore its excellent functionality.

How do I know my knife will last long?

If the knife has superior quality materials in its build, it will last longer.

A stainless steel blade with a coated finish will resist rust and corrosion, thus staying longer.

For the handle, and ABS material or the brand’s proprietary material will make the knife last.

Be sure to also go for rubber-made handles since they’re also very durable.


Some people think that they need to shell out hundreds of dollars for high-quality, task-specific knives like filleters.

But that is a wholly regrettable misconception.

There are many options for premium fillet knives – the type that is thin, hard, yet incredibly flexible – for less than $50.

Yes, you read that right – less than $50!

If you are thinking of getting this any time soon, here are some great options which you should be considering.

Imarku, for instance, has a 6-inch boning knife that isn’t just well constructed, it’s an aesthetic wonder too!

It is made from high carbon steel, fully forged, and features a beautiful Pakkawood handle. And this can be had for just under $30 too!

KastKing is a well-known brand for outdoor gears specifically for fishing, and they have been making great leaps with their blades!

They have a selection of five G4116 stainless steel knives of different sizes that would be great on various kinds of fish.

Bubba, also another brand for fishing gears, has been creating filleting blades that would match pricey ones in style and function.

Their 9-inch curved and tapered blade made from 8Cr13MoV stainless steel with the red rubber handle is so durable, this may be the only tool you will need for prepping fish.
