1. A cutting element, comprising:
a body;
a non-planar cutting face formed at a first end of the body having an impact resistant feature, the cutting face including a central raised region and two raised edge portions; and
an edge formed around a perimeter of the cutting face, the edge having an edge angle defined between the cutting face and a side surface of the body, the edge angle varying around the perimeter of the cutting face, and the edge including an acute edge angle defined by a portion of the cutting face extending downwardly from the edge to a depth from the cutting edge and wherein
the two raised edge portions including first and second sections having different edge angles, with the edge angle of a portion nearest the cutting edge being larger, the portion nearest the cutting edge forming at least a portion of the impact resistant feature.
