Here's something to remember...I've accidentally tried to get through airport security with my blade still in my pocket. BTW I carry a swiss army knife or my Gerber although I am starting to like a Winchester I got as a gift recently. Anyway...I backed out of security instead of letting them have it. Airports usually have a post office. If you can find it, buy a mailer and mail your blade home or to your destination. I'm military so one time in Baltimore I saved postage and left the knife at the USO until I got back...
