Dexter-Russell Dextreme Dual Edge 7-inch Flexible Fillet Knife

Scaling a fish with a fillet knife dulls the edge before the filleting starts. Dexter-Russell solved that on its Dextreme Dual Edge knives by putting a scalloped Tiger Edge along the spine for scales and tougher surfaces, with the plain fillet edge underneath kept sharp for the meat. Flip the knife in the hand and the same tool does both jobs.

The 7-inch DX7F has a flexible blade, and Dexter names snapper, cod, haddock and blackfin tuna among the fish it handles. That makes it a fit for the mixed bag of a New England groundfish trip as well as warm-water fishing. The DEXGRIP handle is ambidextrous and slip-resistant, and a sheath comes with the knife, so it can travel in a tackle bag without a separate guard.

Comparing Dual Edge Lengths

The Dextreme Dual Edge 8-inch Flexible Fillet Knife adds reach for halibut and grouper. For fish that need no scaling, the single-edge Dextreme 7-inch Max Flex is more flexible.
