Abstract
A cutting element may include a substrate and an ultrahard layer. A top surface of the ultrahard layer includes a peripheral edge extending around the cutting element, a cutting crest extending across a major dimension of the cutting element from a cutting edge at a first portion of the peripheral edge to a modified region at a central axis of the ultrahard layer, and a lateral portion extending across a minor dimension of the cutting element from the peripheral edge to the modified region. The modified region along the major dimension includes a concave cross-sectional shape. The lateral portion along the minor dimension from the peripheral edge to the modified region includes one or more of a linear shape and a convex shape, and the modified region along the minor dimension includes a planar shape perpendicular to the central axis.
