Does anyone have one of these tactical pens? What do you think of them? I wanted to get one to take on vacation (flying to ireland), but after looking at them online I'm not so impressed. I've actually ordered an all steel zebra pen to check out. It was only five bucks and should be a nice pen in any case, but I'm thinking it may be a good choice over these ridiculous looking tac pens... Most don't even write! Lol.
