The defining feature of the Assist Salt is its H-1 steel blade and lock bar. This unique material uses nitrogen instead of carbon to create a steel that is tough, holds an impressive edge, and is practically immune to corrosion. The blade&&';;s Trademark Round Hole(TM) ensures swift, positive, one-handed opening, even while wearing heavy gloves. Its blunt tip safely slides under seat belts, clothing, and other materials and will not puncture flotation gear, while its SpyderEdge provides extreme cutting performance that easily powers through even the toughest materials. The Assist Salt&&';;s bright yellow handle is injection molded from tough fiberglass-reinforced nylon and has both a Bi-Directional Texture(TM) pattern and finger grooves to guarantee a secure grip. The finger grooves also provide a solid purchase that enables the blade to "scissor cut" rope much like a cigar cutter. Squeeze the Assist Salt&&';;s closed blade and a retractable carbide glass breaker extends from the butt end of the handle to safely and efficiently break windows. A built-in survival whistle, sturdy back lock mechanism, and a reversible wire pocket clip round out the knife&&';;s features and ensure convenient carry and completely ambidextrous operation.
