Blackdog is right on target. I try to stay fairly inconspicuous, don't wear T-shirts that say, "Kill `em all, let God sort `em out!", be polite and say hello, that sort of stuff, and I haven't had a problem with either a micarta Calypso Jr., a carbon Dragonfly, or a small Sebenza. I usually use the "money clip" approach as well. It seems most security personel are a bit reluctant to touch other people's money, for fear of recriminations concerning theft. That's just my personal experience, though.
Here's a great one. We flew from Detroit to Denver and back for an extended five day weekend over the holiday. What set off flags and questions? A rectangular black about 6" long, 4" wide, and 2" thick, all wrapped fairly tightly in alumunum foil. C-4 or other
plastique, you ask? No, just your innocent, everyday Rice Krispie Treats. LOL! Go figure.
Of course, based on the shape and the wrapping, I can see where they might want to just check for themselves just to be sure.
