A pipe cutting machine shear, historically known as a lever shear and sometimes as a crocodile shear, is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears; however, there are types for excavators. They are generally used to cut ferrous members, such as rebar, pipe, angle iron, or I-beams.
