Sneak this $10 Keychain Tool Onto a Flight for Mid-Air ScrewdriveringS

Let's face it—you're probably up to no good with this keychain tool, which conveniently disguises itself as a key. At about a third of the price of a Swiss Army knife, it has eight handy tools.

That's three different screwdrivers, a pair of tweezers, a wire-stripper, bottle-cap opener, nail file and nail cleaner. It comes with a fake key which the tool hides behind, and a stainless steel key-ring. Just in case the user can't distinguish between a screwdriver and a nail file, the various tools' names are even marked on the key. It's a tenner at ThinkGeek. [ThinkGeek via Uncrate]
