I spotted the Embassy Pen (top image) over at Uncrate and really dig the minimalist Maglite-esque look of it. It's $38.50 from County Comm. I showed it to Rob and he hipped me to the bad-assness of the Smith & Wesson Military and Police Tactical Pen that's just $26 from Amazon. Now if only I could manage to hang on to a pen for more than two days.
