H-1 is an extraordinary Japanese steel that uses nitrogen instead of carbon to create its steel matrix. The result is an austenitic steel that does not require heat treatment, gets harder and tougher with use and is completely impervious to rust! Spyderco"s Salt I combines this exclusive blade material with our best-selling Delica design to produce a handy, do-everything knife that is totally unafraid of the water. The Salt I"s tip features a thicker, more rounded design for increased utility and a large 14mm Round Hole to make one-handed blade opening easier with gloved or wet hands. All other steel components of the Salt I have also been specially treated to make them impervious to rust and pitting. The black fiberglass-reinforced-nylon handle has Volcano Grip texturing to ensure a slip-free grip, and a strong back lock mechanism with David Boye"s locking lever dent provides secure, reliable blade lock-up. A reversible black titanium pocket clip supports left or right-side tip-up carry and a hole through the clip attachment screw also allows attachment of a lanyard when using the knife around water.
