I saw a type of ratchet socket wrench that I haven't seen before.

It's a standard socket ratchet with a direction selector plus,,, at the end
of the wrench handle is a one inch rotating bar that you can turn, which
causes the wrench socket to turn.

In other words, if the nut or bolt is loose, you can turn the socket without
moving the wrench handle.

Anybody know what this type of wrench is called?

Thanks
