Yellow ASSIST
 
The Assist Salt combines the multi-functional versatility of the Assist model with the rustproof qualities of H-1® steel to set a new standard in rescue tools. 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 completely immune to corrosion. The blade’s Trademark Round Hole™ 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™ 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.
 
Double Black ASSIST
 
 
We named this knife after its principal job function, to assist.  The Spyderco Assist Black Blade is a lightweight folder for emergency fire/rescue professionals and the well-equipped citizen who rely on knives to be straightforward in use and perform flawlessly.  The blade is coated in non-reflective black carbon nitride with a patented lift-and-pry (blunt-nose) shape made from high-carbon VG-10 stainless steel and loaded with teeth.  Most of its 3-3/8" (86mm) cutting edge is serrated with the last inch at the tip left PlainEdged.
 
Above the one-hand-open hole sits a feature called a Cobra Hood.  It\\\'s a metal cap that guides the thumb over the hole for quick, by-feel opening then doubles as a textured leveraging platform for your thumb during cutting.  A wavy pattern cut out of the top of the blade and again along the handle is for controlled rope cutting.  By placing a rope in the groove (between the partially open blade and handle) you can squeeze the blade shut, slicing and trimming rope in a controlled movement without fully exposing the cutting edge.  The handle is black lightweight fiberglass reinforced nylon (FRN) with a survival whistle built into the butt end, shrill and high-pitched enough to get you noticed.  A reinforced wire pocket clip attaches through the handle on either side for left- or right-hand use.  A retractable and replaceable carbide-tip glass/ice breaker is housed inside the handle and is exposed when the closed blade is squeezed into the handle, retracting when pressure is released.
