The Rapala Fish 'n Fillet Knives are made by Marttiini, the makers of premium Rapala fillet knives for over 50 years. More guts than any other knife, this is the one that taught the world to fillet. A favorite since the early days of Normark with over 100 million sold to date, this knife is used in more fishing camps, on more charter boats and by more fisherman than any other fillet knife in the world. Progressively tapered, flexible, full-tang blade of European stainless steel that takes and holds an ultra-sharp edge is securely anchored in legendary birch handle. All protected by a fine tooled leather Laplander sheath with "safety-first" free-swing belt loop that always keeps sheath and blade clear of the body. With four blade sizes to choose from, there's one just right for every fish cleaning chore. It includes an easy-to-use single-stage sharpener that keeps blade razor sharp.
