Kershaw's water sports knives feature sturdy stainless-steel construction, yet their open-tang handle design cuts down on unnecessary weight. Both Sea Hunter models offer blades of highly corrosion-resistant 420J2 stainless steel. The injection-molded handles feature neon accents so they're easy to see in a marine environment. Both Sea Hunters and the Amphibian come with the Kershaw Diver's Sheath with quick-release buckles. Add the Clip System, and you can attach the Diver's Sheath to a life vest lash tab, netting, and a variety of webbing.
