Kershaw Narrow Fillet Knife 9.5" Drop Point 420J2 Stainless Steel Blade Nylon Handle Black and Gray

From MidwayUSA

The Kershaw Narrow Fillet Knife is one of the key fillet sizes that every angler will want at the ready. In fact, if you could only have one fillet knife, this would probably be the size to choose since it can handle a wide variety of sizes. For instance, it's perfect for filleting bass or smaller trout, but can handle both larger and smaller fish in a pinch.The blade is razor-sharp 420J2 stainless steel for excellent corrosion resistance-always important for use in a wet environment. The steel is also quite tough and easy to re-sharpen.
