Sir Arcsalot:

Or even just a "crow's foot" attachment for existing socket wrench handles!!! [Linked Image]

Car mechanics already have things like that, so the concept exists. Just someone has to come up with a new die to make them in the shape we need.

Picture the open end of a wrench, but intstead of a handle, you have a square hole. The post from the ratchet handle fits into this and it turns like a regular wrench.

They're a breeze to use.
