The Bi-Polar is very capable. ItÕs also the first dual assisted knife with twin blades. Using patented S.A.T., each blade is propelled out once the operator has initiated the blade opening action. It might be the perfect rescue knife, whether used by law enforcement, emergency medical personal or in your garden releasing the grip of a tenacious vine. We think the Bi-Polar is the perfect combination of might and right with main blade, patent pending V-Cutter, and glass breaker. Our V-Cutter will easily cut seatbelt material, paracord, fishing line, strip most types of wire, zip electrical cable sheathing, open packages, cut nylon banding straps, etc. Dual blades, double lockbars and twin safeties all work to lock the blades closed or double lock the blades open.
