The Spyderco C89SBK Atlantic Salt Folding Dive Knife Satin Serrated. The Atlantic Salt is a great rescue knife that is designed for seafarers, rescue workers, EMT's, ranchers and anyone cutting around flesh in an emergency. This rustproof version of Spyderco's Atlantic Salt is a modified Rescue made with state of the art non-rusting H1 steel. H1 is a precipitation-hardened steel containing nitrogen instead of carbon, which cannot rust. The hollow-ground blade offers remarkable cutting performance in and around fresh and saltwater. The textured black fiberglass reinforced nylon (FRN) handle features Volcano Grip and includes a lanyard hole. Comes with a reversible titanium pocket clip for right or left- handed use.
