摘要：
Cutting elements include a volume of superabrasive material. The volume of superabrasive material comprises a front-cutting surface, an end-cutting surface, a cutting edge, and lateral side surfaces extending between and intersecting each of the front-cutting surface and the end-cutting surface. An earth-boring tool may comprise a bit body and at least one cutting element attached to the bit body. Methods of forming cutting elements comprise forming a volume of superabrasive material comprising forming a front-cutting surface, an end-cutting surface, a cutting edge, and lateral side surfaces extending between and intersecting each of the front-cutting surface and the end-cutting surface. Methods of forming earth-boring tools comprise forming a cutting element and attaching the cutting element to an earth-boring tool.
