Publication number: 20220396722Abstract: A shaped abrasive particle is presented. The shaped abrasive particle has a first and second surface. The first and second surfaces are substantially parallel to each other and separated by a thickness. Each of the first and second surfaces have a surface profile, which includes a plurality of corners and a plurality of edges connecting the plurality of corners. The shaped abrasive particle also includes a recess included wholly within one of the plurality of edges, wherein the recess is a concave void extending into the surface profile.
