Q. What are paper cutter blades called?

Answer

A paper cutter blade also called guillotine and a paper guillotine. It is a common tool in workplaces and classrooms and its purpose is to make clean straight cuts on individual pieces of paper or on stacks of paper. In 1844 French inventor Guillaume Massiquot patented the paper cutter. Years later in 1879 inventor Milton Bradley patented his own take on the paper cutter. Cutters for paper can range in size from roughly 30 centimeters (1 ft) on each side for use in the workplace to 841 millimeters (33.1 in) (the length of an edge of A1 paper) in design studios.
