USED GUILLOTINES

A paper cutter (also referred to as paper trimmer, and commonly misattributed as a "paper guillotine"') is a tool designed to cut a large set of paper at once with a straight edge. In the modern paper industry, larger machines are used to cut large stacks of paper, cardboard, or similar material.
Such machines operate in a manner similar to a guillotine; the blade moves straight up and down, with no rotation around a fulcrum like smaller hand-operated paper cutters.
