Used extensively in bookbinding, a board shear is a big, hand-operated machine for chopping board or paper. Like scissors, a board shear makes use of two blades to use shear stress exceeding the paper's shear power so as to cut. The stationary blade forms the sting of the cutting desk, with the shifting blade mounted on a cutting arm. Originally often called a desk gauge shear as a result of its gauge allowed the slicing of constantly-sized materials, the board shear resembles a bigger version of the paper cutters commonly present in offices. The earliest identified reference to a board shear comes from an 1842 supplement to Penny Magazine, titled A Day at a Bookbinder's, which included a drawing of a board shear with lots of the major developments already present.
