    Abstract: 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.

    Abstract: Devices and methods for well logging using a wear-resistant electrode are provided. A downhole device may include a drill collar and a first electrode mounted on the drill collar. Further, the first electrode may include a wear-resistant face. The first electrode may be movably coupled within the drill collar, and the first electrode may be configured to extend and retract into a wellbore to maintain contact with a wall of the wellbore. Furthermore, the first electrode may be configured to measure impedance of a geological formation.

    Abstract: A downhole tool includes a tool body and an actuator coupled to and selectively extendible relative to the tool body. The actuator has a working face that contacts a downhole formation, and which includes an upper portion and a lower portion. The lower portion has a tapered surface that is directed radially inwardly and axially downwardly relative to the first portion, with at least a portion of the tapered surface including an ultrahard material having a different coefficient of friction as compared to a first material of the upper portion.
