Used extensively in bookbinding, a board shear is a big, hand-operated machine for cutting board or paper. Like scissors, a board shear uses two blades to use shear stress exceeding the paper's shear energy so as to chop. The stationary blade varieties the edge of the slicing table, with the shifting blade mounted on a slicing arm. Originally often known as a table gauge shear as a result of its gauge allowed the cutting of consistently-sized materials, the board shear resembles a bigger model of the paper cutters generally found in offices. The earliest recognized reference to a board shear comes from an 1842 complement to Penny Magazine, titled A Day at a Bookbinder's, which included a drawing of a board shear with a lot of the main developments already present.
