Abstract
A cutting element for an earth-boring tool includes a substrate and a volume of polycrystalline diamond on the substrate. The volume of polycrystalline diamond has exterior surfaces defining a front cutting surface, a peripheral edge, and at least a pair of angled tip surfaces defining at least one cutting tip between the pair of angled tip surfaces. The front cutting surface includes a first planar region and a second planar region, one or both of which may include a cutting tip. The front cutting surface may be characterized as generally concave. Earth-boring tools include a tool body and one or more such cutting elements secured to the tool body.
