Bernard Parallel Jaw Pliers

The image depicts a set of Bernard Parallel Jaw Pliers, a unique hand tool characterized by its compound-leverage design and parallel-action jaws. This specific tool was originally patented by William A. Bernard in the late 19th century, specifically around 1890, representing a significant innovation in hardware design that allowed for uniform pressure across the entire surface of the jaws.

Historically, these tools were manufactured by the William Schollhorn Company in New Haven, Connecticut. The brand and manufacturing rights underwent several changes over the decades; the company was eventually acquired by Sargent & Co. in 1948, which continued production of the Bernard line. Later, in the 21st century, Rostra Tool Company acquired the rights to the brand. Today, the Rostra Tool Company, which operates as a subsidiary of the larger Ideal Industries family, maintains the legacy of these professional-grade tools. While historically centered in the USA, similar designs were produced under license or through subsidiaries in the UK, making it a globally recognized engineering design.
