Description: |
| The screwdriver blade fits in a slot through the handle and shaft of the adjustable jaw. The specifications describe the method of assembling all the parts. A slot on the inside of the adjusting nut allows the screwdriver blade to be retracted when not needed, and a notch on the outside of the adjusting nut indicates when the slots are aligned.
Appears in early 1890s hardware catalogs as the HAINES WRENCH. It is a 4 1/2 inch long pocket wrench. |
