I am usually carrying a Case Stockman, or an Uncle Henry Trapper. These days though you have to be careful about where you are carrying a knife! Last summer my wife lost a small Bucklite knife that she had in her purse at Astroworld! She could not carry it in, and the car was too far away to go back to, so she just surrendered it! It was just a small key chain knife. I'm glad it was not one of the more expensive ones!
I bet the gate attendants at these places have a very good collection of knives!
