Bolt cutter

A bolt cutter, sometimes called bolt cropper, is a tool used for cutting chains, padlocks, bolts and wire mesh. The original use for bolt cutters was, as the name suggests, to cut bolt seals from shipping containers at the delivery point. 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.

There are different types of cutting blades for bolt cutters, including angle cut, center cut, shear cut, and clipper cut blades. Bolt cutters are available usually in 12, 14, 18, 24, 30, 36 and 42 inches (30.5, 35.6, 46, 61, 76, 91.4 and 107 cm) in length. The length is measured from the tip of the jaw to the end of the handle.
