I have a co-worker who ran into the same problem. After she got past security, she just walked over to the gift shop and bought a new fingernail clipper. This is bull anyway. If anyone would ever try to use a fingernail clipper as a weapon on me, I would be more likely to be injured in a fit of laughter. They better start taking our pens and pencils away from us too. If I'm in a fight to the death, and I have first pick of weapons from a pen and a fingernail clipper, I'm going with the pen!!!
