An abrasive tool includes an assembly of tool precursors. At least one of the tool precursors has a continuous polycrystalline diamond, polycrystalline cubic boron nitride, or ceramic material cutting element formed into a blade shape. The abrasive tool can additionally include a setting material, which is configured to attach the tool precursors and form a single mass. The selection, arrangement, and setting of the tool precursors can result in an abrasive tool having a predetermined cutting configuration. Methods for forming such an abrasive tool are also disclosed.
