C'mon, physics junkies.  It's time to discuss -- if you
can.

Here is an image of a common open-end wrench:

Note how the head, or gripper, of the wrench is set at an angle
to the handle axis.

Thus, there are two different possible directions of rotation
that can be used with either end to tighten (or loosen) a fastening
nut or bolt.

Why is the wrench designed in this way?

Is one rotation direction preferable to the other?  If so, why?
