It's truly amazing what some people will try to carry on to a plane. Most of the knives, power tools, scissors, etc. are resold by the TSA at state-run stores like the one in Harrisburg, Pa.
Scissors are very popular among airline passengers, and the Harrisburg store is brimming with them.
At three pairs for a dollar, the store is practically giving them away. Some states sell them by the pound. Teachers buy them by the dozens for their classrooms.
NEXT: Box cutters!?!
