Heh, I once carried my late '70s manufacture Gerber Mark I boot knife (http://www.thegerberknives.com/mark.html http://www.thegerberknives.com/mark.html see bottom) in carry on luggage in the mid-1980s, PEOPLExpress Airlines was in a hurry and didn't want to check baggage on that flight (very streamlined, e.g. you paid by cash or credit card during the flight). I showed it (sheathed) to the guy saying "Uhhh..." and I guess he thought correctly I wasn't going to be a problem and waved me on.
