Patent ID: 8539870

Claim:
An apparatus comprising: a base including an arm selectively movable with respect to the base, the arm being selectively rotatable about a first arm axis towards and away from a substantially planar top surface of the base; a base plate engaged with the arm; and a circular saw having a saw blade configured to be detachably coupled to the base plate, the circular saw being movable with the base plate when coupled to the base plate, wherein the apparatus includes: a first mode with the circular saw coupled to the base plate and the arm being selectively rotatable about the first arm axis; a second mode with the circular saw coupled to the base plate and the arm being constrained from rotating about the first arm axis, the arm being substantially stationary with respect to the base wherein the base plate is pivotable about a vertical axis such that a face of the saw blade is substantially ninety degrees with respect to the arm and vertically adjustable relative to the arm along the vertical axis; and a third mode with the circular saw detached from the base plate.
