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 keyring. 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 $US10 at ThinkGeek. [ThinkGeek via Uncrate]
