Abstract
Abstract An improved diamond abrasive saw blade comprising a steel disc having a plurality of slots and resultant projections at its periphery and a plurality of `L` or `T` shaped cutting segments affixed alternatingly in line inversed to each other at the periphery of said disc is described. Also described is a method of retrofitting prior art worn out used blades with novel cutting segments of this invention.
