I carried Camilus electrician's knives most of my life, from the
start of junior high school, on. I made several flights with one in my
pocket, as well. I simply opened both blades and let them see they were
barely sharp enough to strip wire, wile telling them I used them every
day in my work to strip wire, and as screwdrivers. They just said, Ok,
and handed it back to me.

Have you carried one on a flight since 2001? I always carry a pcket
knife, except when flying...
