On a slightly different note, I flew from Amsterdam to Dublin last week, and while waiting for the flight, bought a silver cake cutter in the duty free shop. It was sharp and serrated, and I was doubtful that they would let me on with it, but the shop promised a refund if there were any problems. Got to the gate, and carry on had to go through x-ray machine again. The cake cutter was in one of the bags and it was picked up by the security person. I was asked what it was and explained it was a cake cutter. The didn't seen at all concerned, and let me take it on to the plane. An you can't carry on a plastic bottle of water.... go figure!
