Until today, when I read an article in the New York Times about the problem orchestras face:
The violin virtuoso and conductor Pinchas Zukerman said security officials had even asked him to remove the strings of his 1742 Guarneri del Gèsu. "I've had unbelievable discussions at certain airports," he said by telephone while waiting at the Atlanta airport for a flight with his wife, the cellist Amanda Forsyth. "They want to stick their hands in my instruments, and they say, 'It's my job.'"

I can't imagine security asking me to remove my blades... though they're welcome to stick their hands in my boot if they like!
