Patent ID: 7739801

Claim:
An undercut saw configured to cut a substantially vertical wall surface while a fixed blade guard moves across a substantially horizontal floor surface on which said undercut saw is placed, said undercut saw comprising: a housing; at least one handle on said housing, a motor housed within said housing; a drive shaft rotated by said motor; a circular saw blade mount mechanically linked to said drive shaft such that when said drive shaft is rotated by said motor, said blade mount is rotated such that when a circular saw blade is mounted on said blade mount, said circular saw blade is rotated; a fixed blade guard joined to said housing, said fixed blade guard circumscribing a portion of a circular saw blade when it is mounted on said blade mount; a depth gauge mountable on said fixed blade guard; and a retractable stabilization bar mounted on said fixed blade guard separately from said depth gauge, said retractable stabilization bar extendable from at least one end of said fixed blade guard, said retractable stabilization bar including a bumper at an end of the retractable stabilization bar, said bumper being a cylinder that is rotatably coupled at an end of the stabilization bar; wherein when said undercut saw blade is mounted on said blade mount, and said blade, said fixed blade guard, and said depth gauge are not in contact with said substantially vertical wall surface, said retractable stabilization bar prevents tipping of said undercut saw by contacting a substantially horizontal floor surface; and wherein said retractable stabilization bar will retract at least as far into said blade guard that the end of said retractable stabilization bar is flush with an outer edge from which it may extend from said fixed blade guard.
