Sorry Sosafan, gotta disagree with you on that. I don't want the confiscation of my personal proprty left to the whim of the security person checking me through. If your wife's scissors were passed through on 3 legs, and confiscated on the 4th leg, then either the first 3 places are dropping the ball, or the 4th place is not applying the rules correctly. I would want to know which it is. I don't object to placing my property in checked baggage, but I want to know what I need to handle that way. I don't want to lose something that I have carried on for 100 flights just because somebody at the 101st security gate decides on a different interpretation of the rules. The rules need to be clear and posted so that you don't lose your scissors and I don't lose my stuff.
'Nuff said.
