Description: |
| The adjustable jaw is held in position by the wedging action of the eccentric end of the shank; the entire jaw portion can be rotated so the adjustable jaw is at right angles to the shank, or parallel to the shank. According to a 1857 Scientific American item cited in Ken Cope's "American Wrench Makers 1830-1930," Witherell offered this wrench for sale from Danville, NH. |
