How To Choose The Best Fillet Knife For Fishing

Blade Material

The first thing you will want to consider when picking out a fillet knife is the material the blade is made from. Because you will be exposing the knife to water you will want a blade made from stainless steel.

Quality stainless steel is rust and corrosion resistant. Choosing a knife made of high-quality stainless steel is especially important if you will be fishing in saltwater as saltwater tends to be highly corrosive to most metals.

Stainless steels like what’s in the Buck 220 or Morakniv Comfort are both excellent choices and are high quality that rust, corrode, or break easily.

Handle and Grip

In the old days, a lot of handles used to be made from wood and you can still find wooden handles on many outdoor knives. However, for a fillet knife, you will want to choose a material like rubber or plastic.

Wood is a bad choice due to the fact that it is absorbent meaning it can absorb bacteria and other nasty bugs, it’s slippery when wet and can break easily.

When looking at handles of various filet knives be sure to choose a material such as plastic, rubber, or other polymers. These materials will offer a better fit and a grip.

A solid grip is extremely important. While filleting fish your hands will usually be wet or covered in blood. I don’t think I need to tell you that handling a knife with wet hands is a bad idea and can lead to accidents. Choose a handle that has a quality grip even when wet.


You may not think a lot about a sheath but they are important, for two reasons. The first is they keep your knife protected. Allowing your blade to stay in quality condition.

The second is safety. You don’t want to be digging around in your tackle box and slice your finger open on a fillet knife that’s just laying in there unsheathed. If your filet knife doesn’t come with a sheath I recommend picking one up.

Blade Size

Blade size is crucial when it comes to filleting fish. You think as long as the blade is sharp you’ll be good to go. But if you have spent time hunting or cleaning game you know that the blade size is critical.

For smaller fish such as crappie, a smaller blade is preferred as it allows for greater precisions. On the other hand fish like trout and bass will require a larger blade. Usually, a blade length of 7 inches is great for larger fish.

You will also need to consider how you will be carrying the knife. If it’s going to live in your tackle box or a small bag you may want to pick up a smaller blade or a folding blade.


A quality fillet knife will be flexible. Flexibility is important when you are working around bones and organs. The flexibility of a knife is determined by how thick the knife blade is. Thicker blades will have a lower flexibility than a thinner blade.

Shorter and thinner blades work great for smaller fish like crappie. A short and thin blade will provide enough flexibility for tight angles that need to be cut. Likewise, for larger fish, a longer blade will be better suited.

Manual Vs Electric

Electric fillet knives exist. These are great for when you have to prepare a lot of fish at once. They even come with interchangeable blades that can be used for various purposes.

If you are used to using a manual fillet knife you may waste a bit of meat trying to get used to an electric fillet knife. They’re also great for working with larger fish and tend to be pretty versatile.

If you are looking for precision and to conserve the meat of the fish a manual fillet knife is a way to go. However, they are more tedious and tend to work well when you only have to fillet a few fish.

If you want the best fillet possible than a manual fillet knife the way to go.

Wrapping Up

One tool every fisherman needs in their tackle box is good fillet knife. A good fillet knife is a must if you plan to keep your catch. It allows you to clean and prep your fish for the cooler or the skillet.

To find the best fillet knife you need to look for features such as blade length, blade material, handle design, and flexibility. These features are important for performing precise cuts from small fish to large fish.

A fillet knife like the Mora Comfort is a great budget option for beginning and experienced anglers alike. Mora makes awesome knives and is definitely worth adding to your tackle box, kitchen drawer or boating kit.

As always thanks for reading and remember...adventure is waiting.

All of my life has been focused on the outdoors. From the days of fishing with my father when I was young, to learning more advanced outdoor skills through the Boy Scouts of America; you could say the outdoors is pretty much my life blood. I enjoy a wide range of activities including camping, survival, fishing, hunting, and bushcraft. I have spent most of my life learning these skills and now I want to pass on my knowledge and hopefully learn even more in return.
