The Spyderco Tasman Salt knives feature a distinctive, curved Hawkbill blade. This specialized claw-like blade originated in the marine/commercial fishing industry for cutting rope, netting, vegetation, and various wet, slippery objects. The arching blade holds these objects against the sharpened edge keeping them from slipping off the tip. The Tasman knife blade is made with state of the art non-rusting H-1 steel that offers remarkable cutting performance. H-1 is a precipitation-hardened steel containing nitrogen instead of carbon, which cannot rust.
