Description: |
| The jaw form and potentially adjustable position of one handle facilitate use as pliers or alligator type pipe wrench.
A ca. 1907 MASON'S COMBINATION PLIERS AND WRENCH offered in a Wright & Wilhelmy (Omaha, NE) wholesale hardware catalog used a very different means to obtain alligator wrench functionality. |
