The UZI Tactical Pen takes something as trivial as a pen and turns it into a potential life saving tool, according to CampCo, which will bring it to the 2010 SHOT Show. The most unique feature of the pen is that it employs the UZI DNA Catcher on the crown of the pen. The sharpened crown on the end can be used to jab or poke an attacker, which will not only cause extreme pain, but it will also collect the aggressor's DNA for future identification. The UZI Tactical Pen is made from high-grade aircraft aluminum and is available in gunmetal gray. It retails for $19.95.
