The jaws on this wrench are not parallel:

Specifically, the face of the movable jaw is perpendicular to the "ways",
but the fixed face is not. But they aren't sprung or worn that way. It
seems that it was made like that. But why? Just plain poor quality? But
that's *really* bad. It's an old wrench, not Chiwandian. It says drop
forged, if that helps.

Another thought ........ that slider is pretty long, indicating that it
could be used for larger heads, hence more chance of tweaking.
