Abstract: A multi-link cutting tool used to cut wire, pipe, cable, tube, chain and the like. The cutting tool utilizes a multi-link connecting linkage between the cutting jaw and the handles to increase the leverage obtained at the cutting edge, to control the relative motion of the jaws, and/or use to control the motion of the cutting edge. With this multi-link connecting mechanism, a smaller and more powerful cutting tool can be made.

Abstract: A guard assembly for an abrasive accessory of a power tool is provided, including a guard shell being associated with a first surface of the abrasive accessory and secured to the power tool around an output spindle of the power tool; and a guard cover being associated with a second surface of the abrasive accessory opposite the first surface and attached to the guard shell at a pivot point having an axis that is at a distance from an axis of the spindle, the guard cover being rotatably movable with respect to the guard shell around the pivot point.

Abstract: A guard assembly for an abrasive accessory of a power tool is provided, including an inner guard secured to the power tool around an output spindle of the power tool, and an outer guard secured to the inner guard at a pivot point along or in close proximity to an axis of the spindle. The outer guard is rotatably movable with respect to the inner guar around the pivot point between a retracted position, where the inner and outer guards together cover a first angular area of the abrasive accessory, and an extended position, where the inner and outer guards together cover a second angular area of the abrasive accessory larger than the first angular area.

Abstract: A table saw has a table, a motor disposed under the table, a carriage connected to the motor, a saw blade supported by the carriage and driven by the motor, a riving knife connectable to the carriage adjacent to the saw blade, and a control circuit for determining when the riving knife is connected to the carriage, the control circuit receiving input from a switch which is engaged when the riving knife is disposed on the carriage. A switch contactor disposed on the carriage may contact the switch when the riving knife contacts the switch contactor.
