Description:
Two specific functions are highlighted in this patent. A hole close to the pivot point serves as a wire cutter, and a sharp edge on the back side of one jaw serves as an insulation stripper for electric wires.

The wire cutter hole appears on six- and eight-inch Billings & Spencer pliers bearing the March 12, 1901 patent mark. A similar wire cutter had appeared in the BILLINGS wire cutter advertised in 1892. The wire stripper feature appears as a sharp inner tooth on one jaw of 12-inch and 14-inch Billings & Spencer pliers bearing the March 12, 1901 patent mark.

The patent is described as an improvement on Herbert S. Pullman's March 25, 1884 patent no. 295,885.

The patent is cited on Billings & Spencer pliers produced early in the 20th Century.
