The Salt 1 folding knife was a revolutionary pocket-sized cutting tool that combined the 100% rustproof properties of nitrogen-based H-1 steel with the high-performance features and benefits of Spydercos third-generation Delica design. Although it earned an extremely devoted following, in some ways it was outpaced by some of the design improvements that make our Delica 4 design even better. Consistent with our obsession with Constant Quality Improvement (C.Q.I.), we decided to revamp the design to create the Salt 2. It combines all the salient features of the best-in-class Delica 4 Lightweight model with the extraordinary corrosion resistance of H-1 steel. These include enhanced ergonomics, a high-traction Bi-Directional Texturing pattern on the handle, and a black-coated titanium pocket clip that supports left or right-side, tip-up or tip-down carry. Unlike the Delica 4, which uses stainless steel liners in the handle, the Salt 2s handle components are molded from solid fiberglass-reinforced nylon (FRN) and fitted with four sets of threaded stainless-steel inserts to mount the four-position clip. All other metal hardware on the Salt 2 is also machined from special non-rusting alloys.
