Patent ID: 8365644

Claim:
A replaceable drywall saw blade capable of reciprocating in-line when mounted to a hand held reciprocating power saw for cutting drywall defining a drywall thickness between a first drywall outer layer and a second drywall outer layer, said blade comprising: a body member having a first body edge and an opposed second body edge; a generally linear first piercing edge angularly offset from the first body edge; a generally linear second piercing edge angularly offset from the second body edge, wherein the first piercing edge and second piercing edge intersect to form a forward point on said blade; and a mounting aperture connected to the body member for releasably securing the blade to the hand held reciprocating power saw; wherein the second body edge defines a non-serrated first segment extending from the second piercing edge and transitioning into a serrated second segment which terminates at a proximal end; wherein the blade defines a length equal to the distance between the forward point and the proximal end of the second body edge along an axis defined by the second body edge, the length being no greater than twice the drywall thickness.
