A security guard at an airport confiscated my razor blades today. I've carried razor blades in my hand luggage since 2004 (inadvertently on the first few dozen flights, knowingly and together with my razor on a hundred or more since I found the blades). Usually the guards want to look at my razor and the corkscrew I also carry, but until today noone has asked whether I might perhaps have any blades for the razor.
He also found, and let me keep, my forbidden shampoo and aftershave. And he checked whether I had a blade in the razor. Such clue. Maybe there is hope for mankind.
