Smith and Wesson’s Military & Police assisted knives are super tough and priced to move. The knife employs Smith & Wesson’s M.A.G.I.C. technology (which stands for Multipurpose Assisted Generational Innovative Cutlery). The blade is deployed by either pushing the thumb stud or by pulling the lever on the spine of the knife. Either way, the knife takes over and the blade automatically opens, locks solid, and is ready for nearly anything.

The SWMP4LB model has a blue finished T6061 aluminum handle with rubber inserts. Black coated 4034 stainless blade with ambidextrous thumb-stud and “auto” flipper. Includes pocket clip and safety.
