Abstract
A bolt cutter has a pair of plates between which pass a pair of front axle pins on which are pivoted a pair of blades and a pair of rear axle pins fixed relative to the front pins and in turn pivotally carrying a pair of handles. The rear end section of each blade is formed with a part-cylindrical seat receiving the cylindrical head on one end of a rigid link having on its opposite end another such cylindrical head received in another part-cylindrical seat formed in the front end section of the respective handle. The parts of the blades and handles as well as the links between the support plates are all of like thickness and snugly held between these plates. A pair of inwardly open part-cylindrical seats formed in the blades between the front pins receive a pin serving to ensure symmetrical movement of the two blades whose cutting portions are spaced apart even when the blades are closed.
