I took 5 small screwdriver tips thru the scanner in carry-on, and they had a heart attack! They were still wrapped in new packaging from tool shop - the short phillips heads ones. ... I was made to go check them in - but off course had no bag, so they gave me a garbage bag, and I put them in, rolled in up about 100 times, and put tape around it they gave me. It was like a medicine ball ... and they had to wait for me to board since I had big checked in bags prior ............... It was a hassle to them! But they did it.
Stupid thing is, the lady before me had a metal spike hair clip, that you could stab pilot in neck, but she got thru. I wouldn't of even tickled you with my screwdriver bits!
