A scoring saw is disclosed for use in association with a main saw blade and disposed forwardly of the main saw blade and rotating in the opposite direction. A mechanical connection transmits the power from the main blade to the scoring blade. The mechanical connection is mounted in a longitudinal casing which is pivotally carried at one end on the axle of the main blade and which rotatively carries the scoring blade at its free end. A support assembly is constructed and arranged to vertically adjust the casing and therefore the scoring blade. An adjustment is further provided to transversely align the scoring blade with the main blade.
