A fillet knife is thinner and more flexible, made for fish. A boning knife is stiffer, made for separating meat from bone in poultry, pork and beef.

Hone it before each use and sharpen when honing no longer restores the edge, often every few trips. Softer steels need sharpening more often.
Can fillet knives go in the dishwasher?
It's best not to. Heat, harsh detergent and rattling against other items dull the edge and can damage handles. Wash by hand in warm soapy water and dry right away.
How do I keep my fillet knife from rusting?
Rinse it in fresh water after use, especially after saltwater, dry it fully, and store it out of the sheath until both are dry. A light coat of food-safe oil helps on carbon-rich steels.

A cut-resistant glove on your non-knife hand is strongly recommended, especially on a boat or when you are learning. It also improves grip on slippery fish.

We compare published specs, manufacturer information and verified Amazon buyer feedback, and weigh blade length, flex, steel, grip, sheath and price for each job. We earn a commission on some purchases, but that does not change the order unless a placement is clearly labelled as a featured partner.
