Every angler needs a quality knife, whether fishing in freshwater or saltwater. The right blade is invaluable for trimming fishing line, cutting bait and filleting fish for the dinner table. Those jobs do not all call for the same knife: a long, flexible fillet blade follows a fish’s contours, while a short fixed blade or folder is easier to carry for line, bait and trimming.
I’ve had the chance to fish in many locations and test many top options. These are the manual fishing knives that stood out, with different choices for the cleaning board and the boat.
Key Considerations
I tested every fishing knife on this list in real-world fishing scenarios. Some I have owned for years; others were more recent additions when I tested them. That meant cutting different types of line, including monofilament and braid, and catching and cleaning plenty of fish. The knives that made the messy job most manageable became my favorites.
- Filleting or boat chores: Choose a tapered fillet blade for skinning and long cuts along a fish. A compact knife such as the Intersect is better suited to bait, line and detail work than replacing a full-size fillet knife.
- Length and flex: Match the blade to the size of the fish. Short blades offer control on panfish; longer blades cover larger fish with fewer interrupted cuts. More flex helps follow contours, but a firmer blade is useful for controlled trimming.
- Wet-hand grip: I looked for a handle that stayed secure when wet or covered with fish slime. Texture, finger grooves and room for a comfortable grip matter more than an impressive spec sheet.
- Corrosion resistance: Saltwater makes material choice and cleanup especially important. Stainless steel and coatings help, but neither replaces rinsing and drying the blade, handle and sheath.
- Sheath and carry: Check how the knife stays in its sheath, whether the sheath drains, and whether it suits a belt, vest or tackle bag. A blade cover is not automatically secure carry gear.

Best Overall Fillet Knife: Toadfish Fixed Fillet
Toadfish’s fixed-blade fillet knife lineup is incredibly versatile, with five to eight-inch size options. I tested the five and seven-inch blades for this article. The main buying link is the 7-inch model; the 5-inch version is the smaller option I used. What I love about these knives is that the sizes don’t feel dramatically different in the hand. Credit the excellent rubberized handles here. During my testing, I felt like the finger grooves were all perfect. The handle gave me superb tip control for delicate work cutting around bones. The 8Cr14 high-carbon stainless steel isn’t anything special. However, the factory edge on both knives was extraordinarily sharp and didn’t wear down, even after over a dozen bluegills.
My main complaint is that the sheath relies on a strap rather than positive snap-in retention. While features like the bottle opener and suction cup for attaching to the deck are nice, I just don’t like the Velcro retention straps. However, I’m willing to give it a pass because I like the knives so much. They are an excellent option for anglers who target multiple species. It’s a very affordable and versatile lineup for both fresh and saltwater.

Best Floating Knife: Morakniv Floating Fishing Knife
Considering the bargain bin price tag, the Swedish-made Morakniv Floating Knife is surprisingly well-made. I’ve owned this knife for four years, and it still looks as good as it did the day I got it. This simple fixed blade is a nifty little fillet knife. I most recently used it to prep some bluegill and yellow perch for the dinner table. The short blade is the perfect length for panfish. I found the factory edge makes clean snips of braided fishing line, too. My favorite feature of this knife is the cork handle. It looks cheap, but it’s surprisingly ergonomic. This handle is also what allows the knife to float. It’s a good option for anyone who has a crowded boat and is worried about losing things overboard.
The main downside of this knife is that it is not a full tang. I also own the Morakniv Kansbol survival knife, and the blade of the fishing knife is considerably thinner. However, I don’t think it’s a deal-breaker. After all, most anglers don’t need something ridiculously rugged anyway. This is a fine lightweight knife for an angler’s tackle bag.

Best Grip: Ugly Stik 7-Inch Tapered Knife
Although Ugly Stik might be best known for its fishing rods, it also makes a solid fillet knife. The standout feature of this knife is its ergonomics. I love the finger groove and rubberized portions. I never had this knife slip while using it, and it was easy to cut thin fillets using this knife. The 8Cr14 stainless steel isn’t anything special, but I’m pleased with the edge retention during my testing. The knife is highly rugged and durable, considering the low price point.
The thin blade doesn’t have as much flex as I expected. Additionally, the sheath of this knife is a bit hit-or-miss for me. I found the retention very tight, and it hasn’t loosened up yet. I also don’t need features like a pull-through sharpener on my sheath. However, I do like the slatted design that makes it easy to dry the inside. This is a solid knife backed by a seven-year limited tools warranty. It’s an excellent budget fillet knife option.

Best Compact Saltwater Knife: Benchmade Intersect
The Intersect is part of Benchmade’s Water line. I’ve had this knife for a while and love almost everything about it. It’s as close to ergonomic perfection as any knife I’ve ever used. I love the rubberized feel of the handle. It’s easy for someone like me, who has perpetual butterfingers, to hold. Benchmade went crazy with the jimping on this one. It extends onto the handle and more than halfway down the drop-point blade. I loved putting extra leverage on the tip of the blade using it. Their use of MagnaCut steel also means that edge retention and corrosion resistance are top-notch.
This knife is expensive, but most of that is in the cost of materials. I also found the drop-point blade undersized for filleting unless cleaning small fish. However, I like it for cleanup work. I cut fillets with one knife and then used the Intersect to remove the rib cage. The edge also makes short work of fishing line. It produced some of the cleanest cuts I’ve ever seen on braid. This knife is a winner deserving of the Best of Category accolades it earned at ICAST 2024.

Best for Casual Anglers: Rapala Fish ’N Fillet
Rapala is another storied fishing brand better known for lures. They make four variants of this fillet knife. I tested the smallest, the 4-inch version. It was ideal for the small yellow perch and bluegills I was cleaning. The Birch handle was surprisingly ergonomic and helped make the knife extremely lightweight. This is a good backup or tackle box knife. Considering the bargain price point, it held an edge better than I expected. It’s not the most flexible knife I tested, but it flexed more than expected.
It's not often that I trash an aspect of a product, but I'm not too fond of this one's sheath. It has zero retention, and the knife rattles around too much. Rapala also includes a cheap pull-through sharpener. I think ditching the sharpener and offering a better sheath would serve them better. Still, the knife is solid and has a great price point. This knife is best for casual anglers who may fillet only a handful of fish each year.

Best Traditional Folder: Case Yellow Fishing Pocket Knife
This nifty little folder has an incredibly pleasing old-school aesthetic. It felt like something I’d find at the bottom of my grandfather’s tackle box. I found that the size of this knife was perfect for cleaning panfish during testing. The blade was the ideal length for some smaller perch I caught. It has a thin profile that works great for creating skinless fillets. I love the small scaler that comes as a bonus tool. It helped get into tight areas along the back of the tail. This knife’s compact profile easily slips into a pocket or fishing vest.
My only real complaint is that the factory edge needed touching up. It was a little dull. This knife is going to be slightly undersized for cleaning some species. However, this is an excellent panfish knife. It’s also a solid gift idea for any old-school angler.

How to Choose the Best Fishing Knife
Start with the fish and the job
A fillet knife earns its place at the cleaning board. A compact fixed blade or folder is easier to keep close for line, bait and cleanup. The tested Toadfish sizes cover a broader range of filleting jobs, while the short Intersect fills a different role. Neither shape is a direct substitute for the other.
Choose useful length, not the longest blade
Longer blades work best on larger fish; shorter blades give more control on panfish and around small rib cages. I usually don’t carry my fillet knives while on the water. Small folding knives and fixed blades are best for the on-the-water stuff.
Balance edge retention and sharpening
A fishing knife does not need a premium steel to work well. The affordable stainless blades here can be practical choices for occasional cleaning and easy touch-ups. MagnaCut adds corrosion resistance and edge retention at a higher price. The edge geometry and how easily you can maintain it matter too.
Do not overlook the sheath
A sheath should cover the edge and suit how you actually carry the knife. My testing found very different tradeoffs: the Ugly Stik sheath was tight, the Rapala sheath felt loose, and the Toadfish relies on a strap. Check retention before attaching a knife to a belt or moving around a boat.
Clean and dry after saltwater use
Rinse away salt and residue with fresh water, dry the knife and let the sheath dry separately before storage. Pay attention to the handle junction and any folding mechanism. Coatings add protection to covered surfaces, but the sharpened edge and damaged areas still need care. Follow the maker’s care instructions for the handle and sheath.
Why Trust Us
I have been fishing my whole life and have been covering knives professionally for the last decade. Over the years, I have extensively fished freshwater and saltwater, using many brands and styles of knives. Through trial and error, I’ve figured out what knives work and what do not. I did hands-on testing of every knife recommended in this article, cutting fishing line and cleaning fish. Knives that did not perform well enough did not make this list.
Final Thoughts
For a dedicated fillet knife, the Toadfish pairs useful blade-size choices with the grip and tip control that stood out during testing. Choose the 7-inch model for more reach or the tested 5-inch for smaller fish. The Benchmade Intersect serves a different purpose: its compact blade is useful for bait, line and cleanup, not a replacement for a full-size fillet knife. The Rapala and floating Morakniv remain practical panfish choices, while the Case suits anglers who want a traditional pocketable tool.
FAQs
What type of knife is best for fishing?
A tapered fillet knife is the most useful shape for cleaning fish. A compact folder or fixed blade is easier to carry for cutting line, bait and other small tasks. Many anglers benefit from one of each rather than asking a single blade to do everything.
What is the best knife for cleaning small fish?
A shorter fillet blade gives useful control on bluegill and perch. I tested the 4-inch Rapala and the short Morakniv on panfish; for larger fish, a longer fillet knife can make uninterrupted cuts easier.
Can a stainless fishing knife rust?
Yes. Stainless steel resists corrosion but still needs cleaning and drying, especially after saltwater exposure. Do not store a wet knife in a damp sheath or a closed tackle box.
