Dogbone Wrench

I’ve used it three years. Keep it in my desk and use it much more frequently than my socket set. I always have the right size wrench handy in a single tool, and it rotates, so it functions more like a socket than a crescent wrench.

Design has been around for years. I own the newer Black & Decker model, but Craftsman makes one too.
