The reversible circular saw blade has a plurality of saw teeth, each tooth having a forward-facing cutting edge and a trailing cutting edge so that the saw blade can be removed and reattached to the circular saw with the opposite face of the blade abutting the saw in order to cut with the trailing cutting edge when the forward cutting edge becomes dull. A top surface extends from the forward-facing cutting edge to the trailing cutting edge. The top surface of each tooth has a radius of curvature at least equal to the radius of the saw blade.
