Planning to clean and eat your catch? A good-quality fillet knife is one of the most important tools an angler can own. The thin, flexible blade is designed to follow the shape of the fish, separate meat from skin and bones and help you get clean, consistent fillets with less waste.
The best fillet knife depends on the species you catch, how many fish you clean, where you clean them and whether you prefer a manual or electric knife. Below are some of our top fillet knife options for anglers who want reliable cutting performance at the dock, at the cleaning table or back at home.

- For consistent power: Bubba Blade Electric Corded Fillet Knife

How to Choose a Fillet Knife
Fillet knives are designed to flex, allowing the blade to glide along the backbone, ribs and skin of a fish. The right knife should feel comfortable in your hand, hold a sharp edge and match the size and type of fish you usually clean.
For smaller fish, a shorter flexible blade provides control. For larger fish, a longer blade helps make smooth, continuous cuts. Electric fillet knives are useful when cleaning multiple fish or larger catches, while manual fillet knives offer precision, portability and simple maintenance.
Manual vs. Electric Fillet Knives
Manual fillet knives are lightweight, easy to control and dependable anywhere. They are ideal for anglers who clean a few fish at a time or want maximum feel while working around bones and skin.
Electric fillet knives speed up the cleaning process and reduce hand fatigue when processing larger catches. Cordless models provide portability, while corded models offer consistent power as long as an outlet is available.

What Blade Length Do You Need?
Blade length should match the size of fish you usually clean. Shorter blades provide more control for smaller fish, while longer blades make it easier to take smooth cuts through larger fish.
- 6" blades: Good for panfish, trout and smaller freshwater fish.
- 7" blades: A versatile size for many inshore and freshwater species.
- 8" to 9" blades: Better for larger fish and longer fillets.
- Interchangeable electric blades: Useful when cleaning different species or multiple fish sizes.
How to Sharpen a Fillet Knife
The best way to sharpen a fillet knife is with a sharpening stone. Hold the fillet knife at about a 20-degree angle and run the blade along the stone in one smooth motion. Flip the knife and pull along the stone in the opposite direction. Repeat until the knife edge is sharp.
Pull-through knife sharpeners are also useful to keep onboard. While they may not be as precise as a whetstone, they are convenient for touching up an edge while you are cleaning fish.
How to Use a Fillet Knife to Skin and Fillet a Fish
- Lay your catch on its side on a fillet table.
- Cut behind the gills and pectoral fin down to the backbone without cutting through the backbone.
- Turn the blade and use the backbone as a guide while cutting toward the tail.
- Turn the fish around and finish cutting the fillet off the backbone.
- Turn the fish over and repeat the process.
- To debone the fillet, carefully cut between the rib cage and the meat.
- To remove the skin, lay the fillet skin side down and insert the knife about 1/2" from the tail.
- Hold the skin with your hand or a fork and cut between the meat and skin at a slight angle.
- Rinse, season and cook your fillet.
Fillet Knife Safety and Care
A sharp knife is safer than a dull knife because it requires less pressure and is less likely to slip. Always cut away from your body, keep your free hand clear of the blade and use a stable fish cleaning surface.
- Rinse knives with fresh water after use.
- Dry blades before storing.
- Use the sheath or case to protect the edge.
- Sharpen regularly to maintain clean cuts.
- Keep electric knife blades clean and dry before storage.
- Store knives out of reach of children.
