I was eating at an Outback Steak (House) located within the secure zone of a U.S. airport the other day when I suddenly realized I was cutting into my steak using a real steak knife - stainless steel, sharp serrated edges, the works. While I would be a little more concerned about some of the kitchen implements (like the bloomin onion device), I was still surprised to see a steak knife.

Did this just slip by the TSA or do you think there is a mechanism to inventory these weapons of mass hysteria should a diner with evil intentions slip one onto a plane?
