A carry-around tool that can pass through airports security (without me even taking it off) is the Tool Belt. It is designed for snowboarders but is useful all the time. The buckle can be disassembled easily (without removing the belt) and gives you a phillips, a flat head and 8, 10, and 11mm hex wrenches (which turn out to have handy standard equivalents). It’s also a good tough and comfy belt which I have been wearing and using since 1999.
