Boltcutter

A bolt cutter, sometimes called bolt cropper, is a tool used for cutting bolts, chains, padlocks, rebar and wire mesh. It typically has long handles and short blades, with compound hinges to maximize leverage and cutting force. A typical bolt cutter yields 20 kilonewtons (4,500 lb_f) of cutting force for a 250 newtons (56 lb_f) force on the handles.
