<p>A blade having (32, 72, 98) a core with heat notches (40, 44, 80, 92) separating wear surfaces and diamond impregnated segments (34, 11, 100) soldered in notches in the wear surfaces (36, 38, 74, 78, 96). The blade is useful to cut and widen cracks or pins in asphalt and concrete surfaces. The wide diamond segments require the mechanical lock of the notches to hold them to the core.</p> |
