10 Best Fillet Knives Reviewed

1. Shun Cutlery Classic

The word ‘shun’ is a Japanese term that is used to describe local and seasonal food when it is at its peak of fresh flavor. This classic boning and fillet knife was handcrafted to maintain this ancient tradition, and it lives up to the hype.

The super sharp 6-inch blade is just narrow enough to glide through the body of a fish for smooth skin and bone removal, and the D-shaped handle provides a sturdy grip for excellent control.

The knife was a bit stiffer than we are used to, and the tip of the blade is a bit too thin to handle tough butchering challenges smoothly.

However, when put to the test, this knife passed with flying colors for deboning fish, poultry, and other meats. The blade also maintains its sharp edge for a long time when it is in use.


2. American Angler PRO Electric

If you love to catch and fillet large and robust species such as redfin, grouper, or muskie, you need a sturdy blade to make beautiful fillets. This is where the American Angler PRO Electric Fillet Knife works wonders. 

This electric fish knife can cut through the most robust bones and separate skin and scale from fillets effortlessly, whether cutting through a tough, scaly fish or a soft-boned one. The trigger switch could be more sensitive and lose efficiency if you use the knife frequently.

Since the switch isn’t smooth, the blade can sometimes remain on, which can prove dangerous. However, bar this small issue, this electric knife used for filleting fish offers an impressive 100 volts of power for fast and smooth filleting. It is also quite easy to twist and turn despite its handle design.

3. Gerber Controller Saltwater Fillet Knife

The next knife on the list is the Gerber Controller 10 inch knife, which boasts an incredibly thin blade that gives you just enough flexibility to slice through tough meat. It’s been optimized for use in saltwater with a corrosion-resistant layer covering the steel.

They use a full tang 9Cr18MoV steel blade so you know it’ll last a while. In other words, you won’t have to work too hard to fillet fish or different types of meat when you have this blade on hand.

This is the best fish filleting knife you can get within its price range.

Best of all it comes with a built-in sharpener that allows for blade touch-ups whenever you find that the knife isn’t cutting like butter. That’s super handy especially when you’re on the boat!

Manufactured in Germany, the Zwilling J.A. Henckels boasts German steel making it one of the best fish filleting knives you can get in the market. The 7-inch long flexible blade is honed to perfection, and it boasts a slight curve near the bolster. Hardened by the brand’s unique ice-hardening technique, the edge on this knife will not stain or chip with use and will also retain its sharpness for years. In fact, all of the knives in this series are made from special steel that has been perfected for 280 years! 

Besides the price (which is on the high end), the only con is the super sharp blade, which is a benefit. You WILL get a nasty cut if you are not careful or are not used to filleting fish. 

One of the great things we loved about this fish knife was the smooth, ergonomic handle.

The Wusthof Pro is a 9 inches long knife that sharpens easily and retains its edge for long periods. Boasting 56 Rockwell hardness, this NSF-certified blade comes with a Santoprene handle complete with a finger guard for smooth and safe filleting action. 

This is one of the best filleting knives fishing sportsmen can get because it comes with a lifetime warranty. This benefit also makes it invaluable for the restaurant and food industry. This knife has no reported cons other than that it can be lethal in unpracticed hands.

Honestly, you shouldn’t be handling a blade of this caliber without some serious filleting experience. The blade is so sharp it can be used to cut off wafer-thin slices of fish effortlessly, provided you have a steady hand.


6. Rapala Heavy-Duty Electric 

Sale
Rapala Heavy Duty Electric Fillet Knife Grey/Black, 7 1/2" Blade
  • Double the speed
  • Three times the power
  • Relaxed grip body

This heavy-duty knife gives you more power, resulting in clean cuts and incredible control when you are filleting big fish. No hacking is required. Cut through backbones and bones without exerting yourself using this easy-to-use knife.

The seven-and-a-half-inch reciprocating style blade is just the right size for all your filleting needs, and the vibration does short work of the toughest fish. Additionally, the grip is ergonomically designed to give you a relaxed grip and prevent fatigue from free filleting. 

The 8 inches-long cord can be a bit troublesome as it can get between your feet as you are filleting. Plus, we also discovered that the blade of this knife could unlock under extreme pressure, and the cord can also get jammed. 

However, the fact that it is three times more potent than other filleting knives on the market made it stand out. Plus, the simple airflow design keeps the motor from overheating.


7. Dexter-Russell SG133-8 

The Dexter-Russel SG133-8 is a real beauty as far as filleting knives go. The sleek, dull yet highly sharp knife is ergonomically designed to reduce persistent stress that may otherwise cause carpal tunnel. 

The soft rubber grip handle allows users to tighten their grip without losing control of the stain-free and high-carbon steel blade, which can slice through meat and bones smoothly.

The only thing that took us a bit aback about this knife was the price, which is higher than other blades in the same class. On the other hand, the knife is surprisingly easy to clean and remains bacteria-free because there is no gap between the blade and the handle.


8. Morakniv Fishing Comfort

Fish knife filleting can be hazardous if the blade you are using is not sharp enough or gets damaged easily. The Morakniv Fishing Comfort fillet knife is a robust and intelligent tool that is flexible and honed sufficient to prevent that from happening.

The long trailing-point blade is made from cold-rolled Swedish stainless steel and boasts a flat grind and high polish finish that you will surely appreciate. The patterned high-friction grip offers a slip-free grip that is rare in budget-friendly blades like this one.

The only thing we didn’t like about this knife was the overly-large handle, which could prove cumbersome in small hands. On the other hand, it also comes out on top as the best knife for filleting fish due to its high-carbon steel blade and heavy-duty build. So, you won’t be disappointed whether you are using it on a boat or in the kitchen.


9. Rapala Fish ‘N Fillet Knife with Sheath

Rapala 6" Fish'n Fillet Knife / Single Stage Sharpener / Sheath
  • The product is Fish 'N Fillet 6" Knife
  • Easy to use
  • The product is manufactured in China

Another great offering from Rapala, this fish ‘N Fillet knife also comes with a gorgeous sheath and a full-tang stainless steel blade that can slice through meat and bone with ease. The long blade holds an ultra-sharp edge, and its length ensures a range of flexibility that is unique in knives that are in this price range. The leather Laplander sheath is perhaps the most attractive aspect of the blade.

You may need to sharpen this knife frequently and before every use, but since it comes with its sharpener, that shouldn’t be a problem. However, that will take away some of the enjoyment of its use.

On the other hand, the ultra-thin blade can hold an edge for a full day of filleting whether you are on a boat or working with it in a kitchen. 


10. Kershaw Clearwater 

Sale
Kershaw Clearwater 7’’ Fillet Knife (1257X), Fixed Japanese 420J2 High-Performance Stainless Steel Blade with Satin Finish and Textured Co-Polymer Black Handle, ABS Sheath Included, 4 oz
  • 7" high-performance Japanese 420J2 stainless steel blade is...
  • Comfortable, basic Black, textured, co-polymer soft rubber...
  • Made in the U.S.A. And Backed by Kershaw limited Lifetime...

The next filleting knife on the list is the Kershaw Clearwater, a knife that is a testament to Japanese ingenuity. The stainless steel blade is solid for filleting large fish, and even if it is on the soft side, the bendable blade does not break easily. Corrosion is not an issue either, which is an invaluable feature if you are filleting saltwater fish. 

The handle fits in your hand beautifully, so you don’t have to work hard to make precise cuts. Plus, there are neon headlights on the tip, so you can always find the knife in the dark without cutting yourself. 

The Kershaw is typically used onshore in a kitchen rather than out on the water because it does not have as much maneuverability as other, more expensive fillet knives.

However, it can be used to cut through tough fish with a few simple strokes, so it doesn’t require much work. 


How to Select the Right Fillet Knife for Fish

There are a number of great knives on the market and if the aforementioned list didn’t help you narrow your choices, consider these features to make an informed decision:

Fishing Fillet Knife Features

The Blade

The blade is the most important aspect to consider if you want the knife primarily for filleting fish. A good fillet knife will have a long, thin, and flexible blade that is easy to maneuver. A stiffer blade will work better for cutting through bone, but it won’t have the same level of flexibility. 

A stainless-steel blade is a good choice because it is less likely to corrode, but a high-carbon steel blade will hold its edge better. 

The Handle Comfort and Grip

The handle of a fillet knife should be comfortable to hold and have a good grip that won’t slip, even when your hands are wet. If you have a knife that is too big or too small, it won’t be easy to handle.

A full-tang knife is always a good choice because it provides more stability. Plastic and molded rubber are ideal choices because of the firm grip, but ensure the handle has a beveled area for your index finger to rest on. Otherwise, your hand can slip while cutting fish, and the blade can nick you. 

Strength and Weight

A good fillet knife will be lightweight, so your hand doesn’t get tired while you are filleting fish. It should also be durable enough to withstand years of use. A thick blade will give you enough leverage to fillet larger fish, but a thin blade will be more flexible and easier to maneuver. 

Size Matters

If you are buying one fillet knife, to determine the size, you should look into look at the size of the average fish you will catch. For example, you can fillet small panfish, perch, and trout with a 6” or 7” knife easily, but with larger ones, an 8” to 9” blade will be sufficient. 

If you are catching both types of fish, keep one of each fillet knife with you. Five inches will also do in a pinch but only for smaller fish. 

Strength

A thick blade will give you enough leverage to slice through dense bones and meat, but it should be flexible enough to slice through easily. 

Frequently Asked Questions

Who makes the best fish fillet knife?

The brands that make the best fillet knives are those that keep the angler’s needs in mind not only out on the water but also inland. Many fishermen like Bubba Blade and Gerber, but there are others that we mentioned above that are worth noting too.

What is the best steel for a fillet knife?

High carbon stainless steel is mostly considered to be the best type for fillet knives.

What is the best salmon fillet knife?

The perfect salmon fillet knife is one that should have a narrow and flexible blade that can run through the length of the salmon and come out the other end quickly.

What is the difference between a fillet knife and a boning knife?

Boning knives are used to remove bone from meat, and filleting knives are used to remove bones and skin from the meat.

Insider Advice

When you are shopping for a quality knife, make sure that you keep the size of the fish you will be filleting in mind. If you get one with a thick blade that cannot slice through salmon, for instance, you will do a hack job on that gorgeous meat.
