Description: |
| A single cutting jaw works in a slotted "double jaw" so the cut removes a thin strip. This facilitates cutting sheet or plate metal, thin metal pipe, etc. as the handles remain clear of the metal surface.
Produced as the BERRIDGE DOUBLE CUTTING SHEARS at Sturgis, MI [along with supplemental crimping jaws patented (no. 594,225) by Philip W. Berridge ] until after the latter's death in 1909, and subsequently by P.S.& W. (and imitators) for years thereafter.
Canadian patent CA-5,953 was granted April 10, 1876. |
