Don’t Fillet Another Fish Before Reading This!

A fillet knife is an essential tool in any angler’s arsenal. They have slightly thinner blades that allow you to get precision cuts on your fish when you clean them. A quality fillet fishing knife also gives you excellent maneuverability to remove the fish’s skin. In turn, you will end up with a single piece of meat instead of a shredded one.

Fillet knives come in all shapes, sizes, and materials. They have a very sharp blade with a fine point that will pierce the fish’s skin and separate the meat from the bone. The blades can range from four to nine inches, and you’ll have to experiment to find the blade size that works best for your fish.

There are manual and electric fillet knives available that you can buy without breaking the bank. Manual knives give you more control, but electric knives take less time to finish larger fish.

How to Choose a Fillet Knife

No matter if you want a salmon fillet knife or a smaller one, you can narrow your choices down using several criteria. We picked out the biggest factors you should keep in mind when you choose your fillet knife and listed them below.

  • Size – As we mentioned, most fillet knives range from four to nine inches long. Many people like to go around seven or seven and a half inches long, but it’ll take experimentation on your part. Try a few different sizes and see which one fits.

  • Strength – Fillet knives are usually more flexible and thinner than boning knives or other game-related knives. You’ll want to double-check the knife’s strength because this will give you an indication of how it’ll bend and flex with the fish when you clean it.

  • Material – You’ll find several different materials in your fillet knife blade. Stainless steel is one of the most popular choices because it resists rust, corrosion, and pitting. Some manufacturers add chromium to their fillet knife blades, and the knives have a Rockwell hardness of 50 and up to make them medium-hard knives.

  • Portability – Another important factor to consider when you’re picking out your new salmon fillet knife is the portability. How easy is it to put the knife in your vest between uses? Check and see if your knife comes with a sheath that attaches to your vest.
