Best Fillet Knife

Do you love to fish? Have you thought about buying a fillet knife so you can easily debone your freshly caught fish?

A fillet knife is lighter than most other knives, and the blade measures four to 11 inches in length. Fillet knives have great flexibility and a blade point that is slightly curved. This makes it easier to make small, precise cuts and maneuver around bones more easily and accurately. It is the ideal choice for skinning and slicing a fish. Fillet knife blades usually have an extremely sharp and thin edge, with an angle ranging from 12 to 17 degrees. It is important to keep this blade sharp, as it is much safer to fillet a fish this way.

Here are a few of the most popular fillet knives available on the market today:

How to choose a fillet knife

You have seen some of the most popular fillet knives on the market today, but what features should you consider when looking to purchase one of your own? Here are a few suggestions.

Blade sharpness

An ultra-sharp blade is safest and will make the most precise and accurate cuts when you are filleting a fish. You will have more difficulty if your blade is not sharp, and may find it hard to separate the skin and bone.

Blade retention

Sharpness at the outset is important but you also want a blade that will maintain its sharp edge over time. This is called blade retention. Knives made of higher carbon metals will retain their edge and stay sharp longer, but of course they are more expensive. If you want to pay less for your knife, consider buying a sharpening tool to make the most of your knife.


Look for the highest quality materials for your price point. A fillet knife needs a blade that is thin, flexible, and strong. If your knife is made of higher carbon metal, it will be thinner and sharper, and the thinner metal will naturally lend itself to increased flexibility.

Also think about the materials used to make the handle. A full tang knife is ideal, especially if the handle is attached to the blade with at least three rivets. This will make your knife strong and durable. Check that the handle is ergonomic, lightweight, and feels good in your hand.

Good luck with your knife purchase. It will be sure to be well used in the years to come.
