How to Choose the Best Fillet Knife

Before you purchase the best fillet knife for your needs, you first have to determine what’s important to you. There are four basic requirements it takes for a fillet knife to be a great one. Let’s look at those three things now.

Sharpness and Blade Retention

Fish are scaly, bony, and thick-skinned little creatures. Navigating around bone and flesh takes a great deal of precision and an extremely sharp blade. The last thing you want is to have to be digging into the fish or apply excess pressure to your cuts. The best fillet knife will be able to slice through fish like butter and maneuver around the dozens of tiny bones inside of the fish.

Contrary to what people think, a dull blade is more dangerous than a sharp one. Finding a knife for yourself that retains its edge and sharpness is imperative so that you’re not wasting time resharpening your knife after every use.

Material and Construction

The quality of the blade and the knife, in general, will come down to the type of material used. High-quality stainless steel is imperative for a solid blade, and rust-resistant and grippy material is necessary for the handle. Your fillet knife will be around water and moisture regularly, so it’s essential that you choose a rust-resistant and waterproof knife.

The handle and the blade are of equal importance. You should always test out the grip and feel of a fillet knife before purchasing one. Everyone has different hands and preferences, and fillet knives aren’t one size fits all. You should feel comfortable and confident with the best fillet knife in your hand for the best results.

Length of the Blade

The length of the blade is something that often gets overlooked. As a general rule, you want a knife blade about half the size of the fish you’re planning on filleting. Because there’s no way to guarantee exactly what you’re going to catch, a happy medium for blade length is around seven or eight inches.

Anything shorter, and you’ll have difficulty filleting larger fish. Conversely, if you have a 10″ fillet blade and you catch a 6″ bluegill, you’ll have just as much trouble filleting it.


As with most things in life, your budget will play a significant role in your final decision for the best fillet knife for you. If you’re a serious fisherman or do lots of cooking, you need to invest in more than just a fillet knife. While it’s essential to choose one that’s high-quality and to your liking, it’s also vital that you don’t blow your entire budget on a single item. Purchasing the best fillet knife for you won’t necessarily be cheap, but it shouldn’t break the bank.

No matter what “best fillet knife” list you look at, the Wusthof Classic Ikon Fillet Knife will likely take the first or second spot on the list.

3. Bubba Blade Stiffie

If you’re planning on catching large fish and filleting them on-site, the Bubba Blade Stiffie is the knife for you.

The Bubba features a 9″ blade that’s thicker and stronger than many of its counterparts. As such, it lacks flexibility, which doesn’t make it ideal for smaller fish. However, for tuna, salmon, and larger fish, this is a clear contender for best fillet knife. The blade is made of stainless steel, and it’s surprisingly sharp for how big and thick it is.

This best fillet knife’s handle has a trigger grip and is made of slip-resistant material, making it perfect for use on a boat or dock. Consider purchasing the Bubba Tapered Flex Fillet Knife if you’re looking for something with a little more finesse and agility. The blade is the same length, but it’s slightly thinner and more agile, making it more suitable for smaller fish.


  • The blade is super strong and rugged, perfect for larger fish
  • The handle style and grip are slip-resistant and comfortable
  • While the edge is slightly thicker than most, it’s razor-sharp
  • You can also use it to dress deer or larger field game


  • A lack of blade flex makes it impractical for filleting smaller fish

4. Bubba Electric Fillet Knife Corded

Manual fillet knives are great for precision and finesse, but if you’re planning to fillet lots of fish in a single sitting, your hand is likely to fatigue. For that reason, fillet knife manufacturers have developed high-quality electric fillet knives for large or heavy-duty jobs. The Bubba Electric Fillet Knife is one of the best.

The knife is trigger-activated, and there is a trigger guard and added safety features that make this knife safe to operate. The handle is ergonomic in design and slip-resistant for added comfort and safety.

The blade is made of tough and rust-resistant stainless steel, designed to withstand the harshest and saltiest of conditions. The handle on this bad boy is contoured perfectly and coated with rubber to make it slip-resistant. The bottom of the handle has a built-in clip that makes this knife convenient for pocket carrying or slipping onto a tackles box or backpack.

Because it’s a folding knife, the Toadfish Stowaway is only partial tang and not quite as strong as its full-tang counterparts. However, in terms of storability, durability, and cutting abilities, this best fillet knife can stand up against most competitors.


  • At only 7″ long, this knife is easy to carry in your pocket or tacklebox
  • The 7″ blade is long and robust enough to handle most cutting jobs
  • The rubber handle is grippy and contoured nicely for comfort


  • It’s only partial tang which makes it more prone to breaking than other knives.
  • While the blade is strong, it isn’t overly flexible and is not the best option for smaller fish.
