Peck Stow & Wilcox Improved Double-Cutting Shears (1915)
|
|
Description: |
| Berridge's metal-crimpers vastly improved the utility of metal shears for sheet metal pipe. The crimping tool forms a new tapered end to allow pipe sections to slip together, after the pipe had been cut to length by the shears.
The dies rock slightly on their attachment bolts.
