The old saying "the pen is mightier than the sword" might actually be true with the Campco TacPen. The TacPen is made of high-grade aircraft aluminum and comes with two different crown attachments. The crown attachments are the sharp and mean bit at the end of the pen made for hurting people.
My favorite quote – "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 aggressors’ DNA which can be used for future identification."
