I am not one for gimmick tools , but this one is just great.
You want the 13 mm metric one, by the way..

Another simular tool [ easy-out design] that Sears has is the set for taking out stripped headed screws. It also works amazingly well...

Specially on aluminum phillips [ you know how those strip] and heavily
painted screws.
The only thing I dislike about the tools is having to watch the Vila commercial...
