Abstract: A power tool for cutting a workpiece including a casing, an auxiliary handle assembly extending from the casing, a motor disposed at least partially in the casing, and a drive transmission operably coupled to the motor. The drive transmission outputs a driving force to a circular cutting blade in response to an input from the motor. The power tool further includes a movable blade guard pivotally coupled about an axis relative to the casing. The movable blade guard includes an inboard surface, an outboard surface, and an edge surface defining a cavity for receiving the circular cutting blade. The outboard surface defines a cam having a camming tip and a camming portion. The camming portion extends substantially along a radial line from the axis.
