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.

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 obviously not my goal when I gear up for a day-long fishing trip, but it does happen.

Brown-trout-release

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 furthermore, 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 that 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 that 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 stringer, or some 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!
