10 Best Fillet Knives in 2027

A fillet knife has a long, thin, flexible blade that bends along a fish’s backbone and ribs, so you can lift a clean fillet and remove the skin without leaving meat behind. A stiff chef knife or boning knife wastes fish and tears delicate flesh.

For 2027 we chose 10 fillet knives, from kitchen knives for salmon and whole fish to sheathed angler knives and a cordless electric model, using Amazon listing details and ratings. For meat and poultry, see our best boning knives on Amazon, or browse all our knife and cutlery guides.

How to Choose a Fillet Knife

Blade length

Match the blade to the fish. A 6-inch blade, like the Rapala or Morakniv, suits trout and panfish. A 7-inch blade, like the HOSHANHO or WÜSTHOF, is the most versatile. For salmon and other large fish, the 8-inch Victorinox or 8.5-inch Mercer lets you take a fillet in fewer strokes.

Flexibility

Flexible blades bend along the ribs and under the skin. Very thin blades, like the WÜSTHOF and Bubba, give the most control on delicate fish. A slightly firmer blade is better if you also use the knife for meat.

Kitchen knife or fishing knife

Kitchen fillet knives, like the HOSHANHO, Mercer and Dexter, have slim handles and no sheath. Fishing knives, like the Morakniv, Rapala and Bubba, have grippy handles, finger guards and sheaths for the boat or tackle box.

Steel and corrosion resistance

Fish and salt water are hard on steel, so look for stainless or stain-free high-carbon steel. Rinse and dry the knife right after use, especially after salt water.

Manual or electric

An electric fillet knife like the BUBBA cordless model is faster for big catches but costs far more. For a few fish at a time, a manual knife is enough. Keep any fillet knife sharp; our guide to the best electric knife sharpeners under $100 can help.

FAQ

What size fillet knife is best?

A 7-inch fillet knife is the best all-round size for most home cooks. Choose 6 inches for small fish and 8 to 9 inches for salmon and large saltwater fish.

Can I use a boning knife to fillet fish?

A flexible boning knife can fillet small fish, but a true fillet knife is thinner and more flexible, which wastes less meat. For meat work, see our best boning knives guide.

Are electric fillet knives worth it?

They are worth it if you clean many fish at once, because they reduce hand fatigue and speed up the work. For occasional use, a manual knife like the Mercer or HOSHANHO is simpler and cheaper.

How do I keep a fillet knife from rusting?

Rinse it in fresh water after use, especially after salt water, dry it completely and store it dry. Leather sheaths, like the Rapala’s, should also be dried before storing the knife inside.

Final Verdict

The HOSHANHO 7-inch fillet knife is our top pick for 2027 because its thin Japanese steel blade handles whole fish and salmon sides in the kitchen and has a large base of positive reviews. The Mercer Millennia 8.5-inch is the best value, and the WÜSTHOF Classic is the best premium choice.

Anglers should look at the Morakniv or the Bubba for grip and portability, and the BUBBA cordless electric knife for big catches. To finish your kit, see our best boning knives and the best cutting boards under $50.
