1. A cutting element comprising:
a body having a base and a cutting face at opposite axial ends and a side surface extending between the base and the cutting face;
an edge formed between the cutting face and the side surface;
an edge chamfer having a uniform size around the entire edge;
a geometric shape formed on the cutting face and defined by a concave boundary with respect to a longitudinal axis of the cutting element, the concave boundary comprising:
multiple rounded vertices, each rounded vertex located proximate to the edge chamfer and forming a cutting tip; and
multiple geometric shape sides connecting the rounded vertices, wherein the geometric shape sides are concave with respect to the longitudinal axis; and

a shape chamfer formed around the entire concave boundary of the geometric shape.
