I was returning from Kenya with a wood carving of 2 lions, they Xrayed that thing, drilled me on what it was, and almost took it away, I'd have rather stayed in New York than let them take it! No one cared in Europe or Kenya, but in the USA a 1 1/2 inch blade pocket knife is a lethal weapon, shoes must be inspected just in case they might blow up, and a 12" kniting needle is harmless, go figure
