I still can't understand why they bother confiscating bladed items when you can walk into any Boots store once through security and proceed to buy razor blades, nail clippers, etc. just before boarding the aircraft.
Best thing I've seen at BAA Heathrow was a pilot having a the knife from a set of cutlery in his flight bag removed at security - he was allowed to keep the fork. Don't really think the Captain would need cutlery should he want to bring down the aircraft he was in command of...
