Spyderco's Rescue knives are long favored by seafarers and the design has since been embraced by rescue workers, EMT's and ranchers-anyone cutting around flesh in an emergency. Now available in a rustproof version, the Saver Salt is a modified Rescue made with state of the art non-rusting H1 steel.Yet another addition to Spyderco's non-rusting Salt Series knife line.  The blades found on all Salt Series models are made with an alloy called H-1.  H-1 is non-rusting premium-performance steel that's raising interest in fishing, boating and diving circles.
