I had to give up a pair of antique embroidery scissors in the Vegas airport. I carried them for fingernails and tag removal - tags in clothes drive me crazy. On the outgoing trip, they were in my checked luggage, but I used them in the motel room the morning we left and dropped them in my purse out of habit. Security would not let me have them. I could go see if I could find my luggage or go buy a mailer and mail them to myself. It was midnight and the plane was due to leave soon, so I had to give them up. They couldn't have been any more than three inches long. I was not a happy camper.
