[origin: WO0001916A1] An abrasive body comprises an abrasive layer (10) bonded to a substrate (12) along an interface (14) and an abrasive projection (20) extending from the interface (14) into the substrate (12) and extending from a point on the periphery of the abrasive layer (10) to another point on the periphery of the abrasive layer (10). The projection (20) has two stepped regions (22, 24), the one stepped region (24) being further from the interface than the other stepped region (22).
