And those just the Canadian rules ... think how much stricter the American rules must be!!
In Canada, I've had the teensiest screwdriver (an eyeglasses screwdriver) confiscated. I was also "forced" to take a drink out of the bottle I carried on board to prove that it wasn't some sort of poison.
In Singapore, a friend of mine nearly lost his cycling shoes when the cleats made the detectors go off - he had to quickly explain what the pieces of metal on the bottoms of his shoes were.
If you fly, you've got to be REALLY careful what you bring with you.
