ABSTRACT:
This invention relates to linesmen pliers, bolt cutters and similar cutting tools which require a mechanical advantage. Durability and long life are prime features of the design. Disk blades are used, and these have cutting edges of two inches circumference, which is about four times the cutting length of conventional straight-blade cutting pliers. The blades are offset and overlapped, thus eliminating separation that occurs with wear. Also, the blades are replaceable; thus the tool can continue to serve the purpose for which it was made long after the original blades become too dull to cut.
As to mechanical advantage, first and second class leverage and a double toggle action are used. The combination of these actions exceeds by far the mechanical advantage of conventional cutting pliers.
