Buying Guide

There are plenty of redfish fillet knives in the market. They differ in quality, size, and design. As such, choosing the right one for your needs can be a bit challenging. Below are the primary factors to consider when shopping.

Blade Flexibility and Size

An ideal knife should be highly flexible. Flexibility allows for easy maneuver during filleting. As such, you can get most meat from the fish with minimal wastage and without injuries.

The size of your blade depends on the size of the fish you are preparing. Most fillet knives range between 4 to 10 inches. However, experts recommend a model that has a blade size of 6 or 7 inches. It is fit for most applications and convenient for transport and storage.

Also, ensure that the blade is corrosion-resistant and is suitable for both fresh and saltwater fish.


A comfortable, non-slip grip handle is an essential consideration when shopping for a filleting knife. These features ensure the product’s safety and make the filleting process easier and quicker.

An ergonomically designed handle could also be an added advantage. It gives you maximum comfort while processing your fish. The handle should also be strong, durable, and easy to clean. You can consider a Pakkawood handle as it fits this description.


If you are an outdoor person, a sheath is an important consideration when buying a filleting knife. It protects not only the blade but also the people around you.

The commonly used sheath materials are leather, plastic, and nylon. Plastic is an excellent choice, as it is quick-drying and durable. But most importantly, ensure that your sheath has ample draining ports and ventilation.

What size of a fillet knife should I buy?

The size of an ideal blade depends on the size of your frequent catches. A small fish needs a shorter blade, while a big fish needs a bigger blade. However, a medium-sized blade of 6 to 7 inches would be an excellent choice for most fishes.

How should I sharpen my knife?

Unlike sharpening a regular knife, you should sharpen your blade in the opposite direction. The tip should hit the stone first before the blade.

How is a fillet knife used?

It is recommendable to slope the blade sideways as you cut. Doing so will give you clean, precise cuts along the spine.

How often should I sharpen my blade?

Sharpen your blade as often as possible. Frequent sharpening prolongs the blade’s edge.

Can I wash my knife in a dishwasher?

Some manufacturers recommend dishwashing your knife. However, this may damage the blade and handle. It also causes it to lose its sharpness quickly. Handwashing is the safest way to clean it.

What is the importance of a fillet knife over other standard knives?

Unlike other knives, this knife delivers precise cuts. It is sharp from the tip to the blade and flexible enough for clean cuts.

Is a fillet knife similar to a boning knife?

No, there is a difference between the two. Fillet knives have slightly curved, thinner, and more flexible blades.


Redfish is always great for meals because one can make several generous fillets, feeding a family of four. Aside from its mild not-too-fishy flavor, this is also slightly lean but flaky and moist – perfect for panfrying or even in chowders and stews.

Perhaps the most onerous part of preparing redfish is carving the flesh off the bone because this has numerous pin bones attached to the spine.

Apart from having the basics of boning and fileting down pat, having the right tool in your hand will make this job easier.

A piece recommended by the experts is KastKing’s filleter made from G4116 German stainless steel. But more than the thin and flexible blade, most users love the contoured polymer handle that ensures a safe and comfortable grip.

For those who aren’t confident wielding sharp knives, electric ones will provide the necessary ‘professional’ assistance.

The Rapala electric fillet knife has a thin, slightly curved, and serrated reciprocating blade that will go through the aforementioned pin bones very easily. This is plugged into a socket.

Bubba Li-Ion is also an electric knife that comes with four different blades. Many prefer this because it is battery-powered so you won’t get bothered by electrical cords snaking around your hand while you’re working.
