A lady I know was waiting to board a plane and as she is a quilter, had a small sewing case with her containing 2 or 3 needles, thread, etc. It was going to be confiscated. She then pointed out men who were waiting to board the same plane who had sharp pointed pins on their belt buckles and asked that the belts be confiscated if her sewing case was; also a lady wearing a brooch pinned to her lapel. After some hasty mumbling among themselves the guards waved her on - WITH her sewing case.
And no, they didn't take the belts or brooch either.
