notes: label: Description
content: John Balmore invented this pipe wrench and cutter tool in 1867. When in wrenching position, a swivel hook catches over the pipe and is held in place with the cup-shaped end of the main shank which can be adjusted depending on the size of the pipe. The cutting piece can be placed in a groove in the inner surface of the end of the shank, keeping it steady without turning the cutter itself. Balmore’s invention highlights the increasing demand for innovative and enhanced hand tools in the latter half of the nineteenth century, driven by the need to handle a wider variety of materials and tasks associated with the expanding industrial workforce in the United States.
