Constructed in collaboration with law enforcement professionals, the Gerber Impromptu Tactical Pen sports a machined stainless steel body with a tempered tip capable of shattering a wind shield or fending off an attacker. It will, of course, write too, inside and out and in any whether conditions, no matter how wet.
