Abstract

An abrasive grain is disclosed and may include a body. The body may include a central portion and 3 radial arms extending outwardly from the central portion along the entire length of the central portion of the body. A first radial arm, a second radial arm, and a third radial arm can define a total angle of less than 180 degrees. The body may also include at least one groove extending from a base surface along a first side of the body.
