Abstract
A cutting element for downhole drilling and related earth-boring tool for downhole drilling. The cutting element may include a substrate and a polycrystalline diamond material affixed to the substrate at an interface. The polycrystalline diamond material may include a raised cutting surface having at least two cutting edges, and first transition surfaces between the at least two cutting edges of the raised cutting surface and a side surface of the cutting element. The first transition surfaces may include multiple planar surfaces.
