Imagine 8 common tools in a package no larger than a common house key. Now imagine that is the same general shape as that house key and will blend in with the rest of your keys right on your key ring. Well imagine no more. The KeyTool Keyring Multi-tool combines 3 sizes of screwdriver, nail file, finger nail cleaner, Bottle cap opener, wire cutter, and tweezers.
While it would probably be a lot more airport friendly if it didn’t have the name for every tool printed out right on the side of the thing, it does look to be pretty handy.
