As a police officer, sometimes the tool that you use most is your pen. For this reason, I chose to purchase the SureFire Pen II. Not only is the Pen II an excellent writing instrument and sobriety testing tool, with its highly polished tip, it's a handy little kubaton, as well. But by far the best thing about this pen is showing other officers, who are SureFire fans too, how big of a fan I am by owning it. The Pen II may not have saved my life (yet), but it has made all the paperwork I have to do much more bearable. Thanks, SureFire.
