I was doing something the other day and needed a 90 deg screw driver to fit into a tight spot and couldn't find my "real" one ... cursed a few minutes, stuck my hands in my pockets and DOH!!! it hit me My Swiss Army knife in my pocket has both a regular and philips driver on it - just open it half way and its a stubby 90 deg driver ou: o No:
I've got a 1/4" ratcheting Craftsman box that I always keep a little piece of gaffer's tape on; I can toss a driver bit (be it a screwdriver, torx, what-have-you) in and put the gaffer's tape on the back side to prevent slip-through. Instant 90 degree ratcheting screwdriver.
