Last Dec. Dublin spotted and confiscated my little folding Swiss nail scissors; I'd forgotten to take them out of my shaving kit. They were a very high quality pair, I still miss them.
They'd passed security at ORD and ATL on my outbound, and I never noticed them in three days in Dublin. So, it seems they have sharper eyes than the TSA's who'd checked me. Yet those eyes still aren't sharp enough to see the rope belt on a girls sweat pants. Pretty seedy...
