The right tool for every job.
Sometimes erroneously called a crescent wrench.
If you have nuts that need rounded off or a hand that needs fresh blood blisters, lay your mitts upon this tool and go to town. You'll come up with curse words never before uttered in the history of mankind as the wrench slips, mashing your hand into something hard and unforgiving.
Fellow 1: What happened to your hand?
Fellow 2: Tried to open a jar with the thumb detecting nut fucker.
Fellow 1: Say no more.

Get the thumb detecting nut fucker mug.
A Thumb detecting nut fucker is like the normal nut fucker just with a separate face for general hammering and bashing thus like any hammer it likes to hit your thumb.
If you can't loosen the bolt just give it a good whack with the old Thumb detecting nut fucker.
