Best Fillet Knives (Overall) 

1. The Gerber Controller 

  • 10 in blade
  • Full Tang
  • 9cr Steel Alloy Blade
  • HydroTread Grip
  • Advanced Vented Sheath System
  • Built-in Sharpener

After questioning ‘hardcore’ anglers from all areas of the sport, Gerber implemented its findings and developed the Controller. 

A robust fillet knife for both salt and freshwater. No matter the technique or target you’re fishing for, the controller will get the job done.  This knife comes with ‘the Gerber lifetime guarantee.

This knife from Gerber is a purposefully designed tool that utilizes quality components that live up to the reputation Gerber has earned through years of experience in the knife business.

9cr steel stays sharp longer and resists rust, and the full tang construction of this fillet knife further adds to its durability. The ten-inch blade can make quick work of even larger fish, so whether you’re harvesting salmon or catfish, this knife is up for the task.

The HydroTread grip provides the angler with a solid and reliable handle even when soaking wet.

The advanced vented sheath is the stand-out feature of this Gerber product. The knife won’t become water-logged when submerged and dries quickly, and there is a built-in sharpener so you can touch up the blade on the job.

Gerber products are designed to last a lifetime, and this knife tops the list for that reason.


  • Quality steel and a full tang make this knife a great tool
  • The blade has a perfect balance of flex and hardness for accurate cuts
  • Advanced sheath with built-in sharpener is very useful


  • The ten-inch blade is a little much if you’re fishing for crappie, but still usable

It is handmade in Germany and forged from a single piece of steel outfitted with a black polyoxymethylene that resists fading and cracking. The finger guard ensures safety and assists with a traditional culinary feel.

This is a great fillet knife set and would make a great gift for the avid harvest fisherman. The blade itself is 6″ and carries all the charm and aesthetic that comes with Damascus steel.

The box contains a sharpening stone, and the set comes with a leather sheath, so you can take it on the water and safely store it back in your kitchen when done for the day. This thing is so pretty I doubt it would ever leave my kitchen.

What makes a good fillet knife?

I must admit I do enjoy collecting knives and having one for various situations is just something that I do. When I started fishing with my father at maybe 14, we kept and cleaned our catch of eastern brook trout, but you hardly needed a fillet knife for them.

Just a normal pocket knife would do, and we cooked them whole, not wanting to waste any of the meat.

When I began my journey into fly fishing, I had already slowed way down the amount of fish I was eating from my local waterways for multiple reasons. I had moved to mostly ultralight spinning gear, and fly fishing would be my next move.

One of the reasons that I abandoned spinning gear and moved to the fly rod was simply because I was mortally wounding trout by way of piercing their gills or worse with spinners attached to treble hooks.

You can imagine my frustration when, suddenly, I would have to race the clock to keep two fish I had inadvertently killed safely from the heat and get back to where I could clean and prepare them.

I started carrying a fillet knife so that I could make quick work of the cleanup job in the field–I had no plans on filleting trout with it.

The fillet knife I chose, and the one that would stay on my belt until I fully embraced catch and release, was a Rapala like the one reviewed above.

ERic Trout

I snagged it at an auction for a low price, and it had been used so much that it was roughly five inches long. That knife performed numerous cleanup jobs with ease, but I also used it for darn near everything that you’re not supposed to use a knife for.

I cut monofilament and braid with it, I cleaned the knots off lures with it, I ate with it, I cut lodged treble hooks out of my clothes with it, cut bait with it, and so much more. I still have it, though I rarely take it fishing anymore.

I’ve gotten a lot better at not harming fish as they cross paths with me, and a pocket knife truly would suffice if I had to harvest a fish now.

Ask yourself what you need out of a fillet knife and buy accordingly. It doesn’t have to be the newest model on the market or electric with a million settings. Find yourself a purposeful, intuitive knife design that you like, and you’ll treasure it.

Electric Fillet Knives Vs. Traditional

A short note concerning electric and traditional fillet knives–filleting a fish requires practice, and while an electric knife makes this process easier (and more easily repeatable), that does not mean that it is necessary to use when you and your buddies are trying to do a fish fry.

Like all things related to or concerning fishing, being able to cut a great fillet takes effort and practice, but when you do master it, cleaning up your catch at the end of the day is light work.

Still, an electric fillet knife can make that repetitive and sometimes painful task of cleaning up panfish a whole lot easier. Save yourself from inevitably getting poked by the spines that are ever-present on perch, crappie, bluegill, etc, and wear a cut glove while using your electric knife. Work smarter! Not harder.

How to fillet a fish

How to sharpen a fillet knife

A Note from a Catch & Release Angler

I started fishing for eastern brook trout at a young age with my father. I wasn’t fly fishing, merely floating a worm, but hiking the same high-mountain streams that my grandmother fished with a cane pole with my father got a fly rod into my hand early.

These fishing trips always ended with trout for dinner, we always kept our limit, and my father prepared them whole afterward (no fillet knife needed).

Much has changed since then. I am more than fifteen years older than one, and now alarmingly dedicated to fly fishing and the philosophy of catch and release. My flies are almost always barbless, as small as I can manage, and I exercise the utmost caution when bringing a fish to hand and then releasing it back into the water.

However, I still carry a fillet knife on my fishing trips, and the reason I do is that inevitably, there will be times that I wound a fish and it needs to be harvested out of mercy. This is not my goal when I gear up for a day-long fishing trip, but it does happen.


Even though you too may be committed to catch and release, there are times when putting a wounded trout back in the water will only increase its suffering and end up wasting this natural resource (although the raccoons will be delighted to find it along the banks).

To other CnR anglers, keep reading. You too might benefit from a good fillet knife on your wading belt, even if it ideally will never be used on the water.

Conclusion/Reeling it in

I’m a knife guy, I admit it. I like to have a belt knife or multi-tool by my side any time I venture out to fish, hike, or just enjoy the outdoors. Knives are the one tool that has near-endless applications for us humans, especially for anglers.

While the majority of my harvesting days are over (unless I finally manage to make it up north to Canada or Alaska) for those of us who participate in that part of the sport, a fillet knife is extremely necessary.

They’re good to keep on hand, even if you are committed to catch and release. Don’t let your day trip be cut short because you harmed a fish and need to get it out of the August sun!

Carry bags, a fishing cooler, or a stringer to have a way to preserve a fish should you have to keep it. Any knife is better than no knife when you need one, and I hope you found a knife in this review that checks all the boxes, so you can buy with confidence.

Tight lines my friends!
