Abstract
A plunge saw comprising a body housing enclosing a motor wherein the plunge saw rotates about a forward pivot point while a lower cutting base bottom planar surface remains in contact with a workpiece. A saw blade is operatively coupled to the motor, wherein the saw blade plunges into a workpiece in a rotational arc thereby exerting both a lateral and vertical force that reduces the likelihood of saw kick back. The saw can be turned on, operated and turned off with a single hand.

A method of operating a plunge saw comprising;
- setting a saw blade depth of cut and a width of cut;
- holding saw with one hand while placing plunge saw base on a workpiece approximately where a plunge cut is to be made thereby activating tongue to release lock member;
- activating the switch with the one hand to turn the saw “on”;
- rotating the saw around a pivot point in a forward end of the saw to plunge a saw blade into the workpiece at a desired location by applying a rotational force with the one hand;
- moving the saw along a desired path until the plunge cut is complete and removing the saw blade from plunge cut with the one hand;
- and
- moving the switch with the one hand to turn the saw “off”.
