Mercer Genesis 7-inch Flexible Fillet Knife

Filleting a trout, a bass or a snapper goes best with a blade that bends along the backbone and lies flat against the skin. The Genesis 7-inch Flexible Fillet Knife does both, with the stability of a forged blade and a Santoprene handle that holds when the hand is wet with water and fish oil.

The flex lets the edge ride over the rib cage, and the same flex keeps the blade flat when sliding between skin and flesh. The fine tip starts the cut behind the head.


Fillet or Boning?

For poultry and meat, a shorter Genesis 6-inch Flexible Boning Knife is easier to steer around joints. The Renaissance 7-inch Fillet Knife is the riveted-handle alternative. The kitchen knife shapes guide explains boning and fillet knives.

    Care

    • Wash by hand after each use with warm water and a mild soap, then dry with a soft towel. Mercer advises against the dishwasher: heat can break down the handle, and caustic detergent can stain and pit the blade.
    • Do not leave the knife soaking. If chlorine or bleach touches the blade, rinse it off at once.
    • Avoid long contact with aluminum pans or a stainless steel sink, and do not leave the knife standing in condiments held in metal pans. Prolonged contact can cause pitting.
    • Store the knife in a block, on a magnetic bar or in a knife guard.
