Worst I had was airport security in the UK stopping me because I had a small swiss army knife on my keychain. My luggage was already checked in and I sure as hell wasn't throwing it away because they were afraid I'd MacGyver my way to hijacking the plane. I ended up mailing to myself.
Yeah, I had the same thing once, except it was with a pocket retractable screwdriver, and I was travelling domestically in Canada. Land of the free, yup.
