A cutting element includes a substrate that is axially symmetric about a central axis. The substrate has a radius perpendicular to the central axis and that extends from the central axis to an outer surface of the substrate. A super-hard material is coupled to the substrate, and the central axis passes through the super-hard material. The super-hard material has an external surface defining at least one ridge protruding from a remainder of the external surface. A central point on the central axis is offset from the external surface of the super-hard material by a distance equal to the radius of the substrate. A distance measured from the external surface of the super-hard material to the central point is greatest at a position between 25° and 45° from the central axis of the substrate.
