How to Choose the Best Fish Fillet Knife

There are a few things you need to consider before settling for a fish fillet knife set. Besides checking out fish fillet knife reviews, you also need to keep an eye out for some specifications. Here are a few features that might help you out.

The Type of Knife

Manual knives are not the only kind of fish fillet knives available in the market. With changing technology there have been improvements in filet knives as well. Electric-powered knives, Manual knives, and traditional knives are the main kinds available nowadays.

Electric knives are faster and more relaxed. You won’t have to use much effort when cutting fish with this knife. But, they are more expensive and require a lot of practice.

Manual or traditional knives are easy to use but you will need to put in a lot more effort. These are cheaper and easier to maintain as well.

One other benefit that these have over electric knives is that they don’t require any power source. So they can be used anywhere. This is also the kind of knife you want to take on a destination, work, or vacation.


Dull blades cause more accidents than sharp blades. So no matter what kind of knife you get, you must always try and keep it sharp at all times. Buy the best fillet knife sharpener to keep your tool in good condition. You can also try and go for knives that don’t go dull too soon.

We have knife options that stay sharp for a long time here in our fillet knife reviews.  The length and size of the blade is also a factor that needs to be considered. Bigger fish will require longer blades to penetrate the meat completely, while smaller fish can be filleted with thinner, smaller knives.


The handle of the knife you are using will increase both your efficiency and comfort. If you have to fillet fish quite often, you should get knives that come with a grippy and more comfortable handle.

Wooden or rubber handles are a great choice for this. A bad handle might cause your hand to slip and cause accidents. So, this is not a feature that you should take lightly.


Fish fillet knives are quite sharp. So, a sheath is a must-have if you want to keep the fish fillet knife in your house or a workstation. You can sheath that are made of leather or rubber. These look quite cool and keep you and the people around the knife safe at all times.

Fillet Knife Vs Boning Knife

Although some people use a boning knife as a fillet knife and vice versa it is not the right method.  Both of these knives serve different purposes. Boning knives are used to separate the fish meat from the bones. So, they are a bit more rigid and thicker.

Fillet knives on the other hand are used to separate fish meat from the skin. Even the best boning knife can’t separate fish from the skin because it isn’t precise, thin, and sleek enough. So, you better use a boning knife if you don’t want bones in your fish fillet!

Fillet knives can sometimes look quite similar to boning knives as well. But the sharpness and curves are different. A fillet knife can’t be used to debone a fish. Fillet knives are designed to slide in between the skin and the meat of the fish to separate them.

The only time these knives can be interchanged is if you are camping or if you don’t have any other tools with you. If you have a small fish that you want to fillet with a boning knife, you can. But we can guarantee that you’ll have skin left on the meat if you’re using the knife on a larger fish.
