Actually, I have a fundamental problem with this trend towards zero-tolerance enforcement of ever more overzealous laws -- they're trying to present a tough image, but doing it by picking on the easy (and wrong) targets. This is not "being so careful", this is more like the proverbial guy looking for his keys under the lamppost because that's were the light is best, rather than looking where he actually dropped them.
Remember, the cause of the Lockerby bombing was not that bombs were openly and cheerfully allowed on airplanes, it was that an existing "no bombs allowed" law (quite a reasonable thing to have for airline flights) wasn't adequately enforced.
Taking SAKs away from people doesn't make the flight any safer, it just gives the government/airlines a cheap, ineffectual, way to appear to be doing something about a much publicized problem, at the expense of chipping away a little more at people's personal freedoms.
A Spyderco Dragonfly ought to be cheerfully passed through an airline's security check as being an obvious utility tool that poses no real threat to the safety of the plane or its passengers. Anybody fool enough to try to hijack an airliner with a Dragonfly should be punched repeatedly in the face by a nearby passenger, and then arrested upon landing.
Ha, but that's just my $0.02...
To get back more on the original topic: I haven't flown in quite a while, but I have been through the security checkpoint in San Diego's Lindbergh airport fairly often to pick up / drop off friends. For the past few years, my standard airport carry has been a small Sebenza, which I put in the change bowl, along with my wallet, key cases, Micra, cell phone, and PalmPilot. They don't bother at all with the Sebenza, though they do want me to turn on the PalmPilot and cell phone to prove that they aren't bombs (which seems lame -- they're not big enough to do much, but on the other hand, one could always rig just enough electronics inside to put up a static picture on the screen, so their test seems pretty pointless). I rather strongly suspect that, for this airport, either my zytel or CF Dragonfly (both plain edged) would draw little more attention than the Sebenza.
