Alligator wrench

The jaws were fixed so that the opening between them was V-shaped. The inside surfaces along the V were serrated so that, in principle, any size nut could be slid along the V until the serrations on each side could grip it. In practice, the wrench really did not work and was generally quickly discarded.
