Abstract: In various embodiments, the present invention provides a structured abrasive article. The structured abrasive article includes an abrasive layer disposed on a backing. The abrasive layer includes shaped abrasive composites, which include abrasive particles dispersed in a polymeric binder. Each of the shaped abrasive composites independently includes a contoured base, which includes a first end disposed on the backing, a second end, and a plurality of sidewalls connecting the first end and the second end. A plurality of walls extends away from the contoured base. The abrasive article additionally includes a grinding surface, which includes a plurality of cusps and a plurality of facets that contact a recessed feature capable of being contained within a geometric plane. A portion of the recessed feature is disposed closer to the contoured base than is each of the cusps, and each cusp is formed by an intersection of two of the walls and a facet.
