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.

Peck, Stow & Wilcox was advertising the No.2 Improved Berridge Patent Double-Cutting Shears in 1915.
