How about tactical pens? Has anyone made it on a plane with one? Are they allowed?
I've taken them on planes many times. I've only had a problem once, in LA: Bag went through, they sent it through a second time, searched it, removed the pen, send the bag and the tactical pen (Tom Anderson Ti Twister) through separately. They gave them back to me and let me continue. (actually, they gave me the bag, and the shoulder strap snagged the bowl the pen was in, sending it skittering across the marble floor. I winced, they shrugged and handed me the pen. I didn't find any damage)

What pen might look like (not my exact model, but mine is of the same series)
