And at Disney World, we're in seatbelts a lot. While I'd trust the CMs at the controls with my life much sooner than I would any given driver on the Florida highways, if worse comes to worse and we're on a ride with belts that can be cut and we've gotta bug out, it'd pay to have the ability (paranoia is just another word for longevity).
A 3" folder is pretty much the standard legal limit in most places in the US, but by all means, check out your local rules and regs before you take to carrying anything, and be sure to look up every definition for the thing as you can think of (a "knife" is a tool that can function as a weapon, whereas a dagger is a stone-cold weapon, and its only purpose is to cut people into tiny little ribbons; for example. Yeah, the law has a lot of loopholes like that). Some useless trivia for you on this one--maybe it's changed by now, but last time I checked, carrying a concealed hangun in Los Angeles is a misdemeanor, but carrying a concealed blade is a felony (the idea is that nice people don't carry knives).
