The Uzi Tactical Defender Pen could easily be one of James Bond's nifty gadgets. While it does function as an ordinary writing instrument, it's also a pen with a glassbreaker on the tip. Made from lightweight aircraft-grade aluminum, it also features a DNA catcher and a built-in handcuff key. Along with its sturdy pocket clip, retractable pen tip and sure grip, it's truly a bad ass self-protection tool with practical everyday applications.
