Dexter-Russell manufactures a variety of knives designed for cutting, gutting and splitting or chunking fish or prying open shellfish. From the blunt-tipped scallop knife, and the traditional small-bladed fish knife, to the large fish splitter, Dexter-Russell has different-sized cutlery depending upon the task, and the fish, at hand. You can even use the 12-inch Dexter-Russell fish splitter knife for chunking small or mid-sized fish for bait for catching larger quarry, such as shark.
