The blade is made of Japanese 420J2 stainless steel with just the right degree of flex to make the job of filleting simple. This softer steel enables the blade to bend without breaking so that it moves easily through the body of the fish to give you the ideal fillet. Plus, the steel is highly corrosion resistant. The handle is durable and contoured for filleting comfort. Neon highlights in the handle make it easy to spot in a marine environment. The co-polymer handle material provides an excellent grip and its soft-yet-firm texture makes the job of filleting even a large catch less fatiguing. The Kershaw Fillet locks into its own ABS sheath for secure storage or easy belt carry.
