Fillet knife buying guide: How to choose a fillet knife

Caught a nice fish? Nothing better for an angler than fresh fish after a day on the water.

Choosing a fillet knife may seem complicated, but its nothing compared to actually filleting some fish the first time. Most fillet knives have somewhat of a standard look, shape and length, so what is the difference between a good and a bad knife?
The truth is, you can “fillet” a fish with any knife, but having the right knife will make your life easier, let you waste less to no meat and will help you not to injure yourself.

What’s the difference between a regular knife and a fillet knife?

There are a few key differences:

  • The shape
  • The flexibility
  • The grip


The first thing you’ll notice when comparing a fillet knife and a regular knife is the shape. Fillet knifes tend to be narrower, with a thin, longer curved tip.


Simply put, the thinner a knife’s blade is (normally), the more flexible it will be. You’ll want a flexible knife because it will help you get cut and slice much easier. Longer knives tend to be less flexible, while shorter knifes are usually more flexible, this is because the more metal there is on a blade, the less flexible it will be, and a longer knife is usually better a little more rigid, while more flexibility is wanted on a shorter knife, which helps filleting shorter fish.


The grip on a fillet knife is extremely important. Something that fits your hand, not too big or too small, something comfortable and not slippery is wanted. This will help you when water, blood and fish slime are all over your hands. You want to feel secure, that your hand is not gonna slip. You do not want to be cut with a fillet knife.

Some fishermen prefer the classic look of wooden handles. While certainly functional, wood can get very slippery when wet, which is certainly dangerous and can lead to bad cuts. Wood also tends to soak up fish smells.

Plastic and Rubber are both excellent alternatives. While both don’t hold smells and are easier to clean, plastic is the best of the two for cleaning, while rubber offers a much more efficient, comfortable grip.

Some knives also offer recessed finger grips. These are not a necessity. While they may work great, you’ll have to make sure to try the knife in person before buying to have the correct size fit.

What size fillet knife should I get?

That highly depends on what size fish you’re gonna clean / skin. Bigger fish, bigger blade, smaller fish, smaller blade. Fillet knife blades range anywhere from 4″ to 9″ usually, with standard sizes being 4″, 6″, 7.5″ and 9″.

Is there a one size-fits-all for blade length?

Yes and no. Like we said before, any size knife will work, but having the right tool for the job makes all the difference. If your primary target is Bass or Trout (yes you can eat bass!), you’ll probably gonna look for a 7.5″ blade. If you’re going for pan fish, the likes of bluegill, crappie, perch, sunfish, pumpkinseed, etc, a 6″ should be best. Bigger fish such as Salmon or Pike would be better suited for something close to a 9″ blade. If you’re only gonna have one knife, go for a 7″, 7.5″. This gives you some flexibility, but no too much, so it’ll work with smaller and bigger fish.

The material for a fillet knife

Stainless steel is the standard metal. There are plenty of different alloys available, but anything in stainless should be great as it is highly corrosive resistant. It will rust, unlike what most people think, but it usually takes a very long time, unless contaminated with other ferrous, rust-prone metals.

Why are the blades of fillet knives plain?

The plain edge on a knife is much better for push cut. Superior control, accuracy, and clean cuts no matter the type of cut or slice needed.

A serrated edge works better for slicing cuts, harder surfaces, bones. Much less control and precision, which is why it is not a choice for fillet knives.

Knife sheath

A knife sheath is really only necessary when on the go. On a boat, camping or when fishing from shore, it is handy to have a spot when you can keep your knife easily accessible and more importantly, a safer place to keep you from getting injured. When at home, you can just put the knife away in your kitchen.

Sharpening stone

Any knife will eventually get dull. A sharpener is a must have. You don’t have to be rough, a few light swipes before every use, or after, and you’ll keep your blade sharp for when its needed. Here’s a helpful guide.

Are electric fillet knives any good

Very much so. If your’re filleting fish occasionally, these are more of a luxury, but if you clean fish everyday, an electric fillet knife might be the perfect pick. These will make the amount of effort in filleting a fish be reduced significantly.

What fish can I fillet?

Not all fish, but certainly many, many fish. Some of the most common are Trout, Striped Bass, Sunfish, Tuna, Dorado, Salmon, Cod, Pike, Catfish, Sturgeon, Mackerel, Tilapia, Crappie, Flounder, Grouper, Carp, Halibut and many, many more. No matter what fish you catch, making sure you have the right gear will save you lots of headaches, and maybe a stitch or two.
