Abstract
A circular saw blade is disclosed with narrow radial slots to avoid tangential stress. In order to lower the noise level and the cracking failure risk, a narrow arcuate cutout is provided in the direction of the slot adjacent to at least one end which cutout is not continuous with the slot. The parts of the cutout closest to the slot comprise at least one of the ends of the cutout, and the distance from the slot end to the nearest end of the cutout is less than the blade thickness.
