Buying tips in 60 seconds

Choose a fillet knife by matching blade length to your fish (6–7" for most freshwater, 8–9" for salmon and saltwater), pick a flexible blade for small fish and medium flex for big ones, and get a non-slip synthetic handle. In saltwater, add corrosion-resistant steel and a sheath that drains.

Blade length by fish

Are electric fillet knives worth it?

Yes, if you clean many fish at once: an electric knife is much faster and easier on your wrist. For a few fish at a time, a manual knife is cheaper and more precise. Our top electric pick is the BUBBA Li-Ion Cordless Electric Fillet Knife.
