I like to travel light when I fly, no baggage to check, so I was wondering, will there be any problems if I bring calipers with me as carry-on? I'm flying domestic US, if that makes any difference. I've had enough stuff confiscated that I'd like to double check before I donate anything else to TSA. I'm sure you could technically stab someone with calipers, but then again, a pen would probably do more damage.
