The TSA is broken anyway. I always carry a full size spyderco knife and have been for so long I dont even think about it anymore. It has a wire pocket clip thats dark so its hard to tell I jave a knife against dark jeans. On my way back from Vegas I made it all the way through security and to my gate before I realized I had it on me. Its a pretty dang good sized knife and wasnt picked up by any of their equipment. Needless to say I dont feel too comfortable about my safety on a plane as far as the fearless TSA thwarting any attacker.
