Abstract: A saw blade, such as a snow saw blade, for cutting heterogeneous, friable materials that includes a fracturing member positioned in the extending line of cutting teeth of the blade, the fracturing member providing a non-cutting impact surface projecting outwardly beyond the outermost line of the cutting teeth to momentarily interrupt cutting engagement during sawing of a surface with a non-cutting, impacting engagement therewith to shatter and break the surface as it is being cut for a more effective sawing operation of the cutting teeth.
