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 20kilonewtons (4,500lbf) of cutting force for a 250newtons (56lbf) force on the handles.
      There are different type 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 in length. The length is measured from the tip of the jaw to the end of the handle.

      * Angle cut has the cutter head angled for easier insertion. Typical angling is 25
         to 35 degrees.
      * Center cut has the blades equidistant from the two faces of the blade.
      * Shear cut has the blades inverted to each other (such as normal paper scissor
         blades).
      * Clipper cut has the blades flush against one face (for cutting against flat
         surfaces).

      Many companies manufacture bolt cutters with fiberglass handles which can be used for cutting live electrical wires and are extremely useful during rescue operations. The fiberglass handles have another advantage of being lighter in weight than the conventional drop forged or solid pipe handles.
