FORGET IT ... I don't trust 'em. :-)
They took a perfectly nice multi-tool (with a tiny blade) from me in Salt Lake three years ago. I was not a happy camper - that thing was a gift. :-( No way I'm getting burned on that one again.
So if my plane crashes and the passengers are forced to EAT each other in a survival situation ... all because no-one had a decent knife ... well I told ya' so.
HAHAHA!!!
