Gerber Impromptu Tactical Pen
With a rather intimidating look, the Gerber Impromptu is very unlike any other pen that you have ever written with. Inside the rugged and precision machined steel body is an ink cartridge that is waterproof you can actually write with it even in the rain or underwater. Its pocket clip, made of high-grade stainless steel, keeps the Impromptu handy. But what sets the Impromptu from the rest is its tempered steel glass breaker tip, giving you the perfect handy tool to get off in any dangerous situation. And if worse comes to worst, its pointed tip can sure immobilize an attacker.
