The Uzi Tactical Pen is arguably better then any pen weaponry that James Bond used. With a DNA collector, stabbing abilities and a body made from aircraft aluminum (not to mention the ability to write), the Uzi Tactical Pen is just plain badass. The DNA catcher, although highly unnecessary, is amazing.
The aforementioned DNA catcher comes at the crown of the pen and looks like it could seriously hurt someone with its sharp blades. Due to its durability, the DNA catcher part of the Uzi Tactical Pen doubles as a glass-breaker. As if this pen weren't clever enough, it even writes underwater.
