A cutting element for an earth-boring tool, comprising: a substrate base comprising a substantially cylindrical outer side surface and a longitudinal axis substantially parallel to the substantially cylindrical outer side surface; and a cutting tip comprising: an elongated surface defining a longitudinal end of the cutting tip; a first generally conical surface extending from proximate the substrate base to the elongated surface; a second generally conical surface extending from proximate the substrate base to the elongated surface, the second generally conical surface opposite the first generally conical surface; a first generally flat surface extending between the first generally conical surface, the second generally conical surface, and the elongated surface; a second generally flat surface extending between the first generally conical surface, the second generally conical surface, and the elongated surface, the second generally flat surface opposite the first generally flat surface; and a central axis extending through the cutting tip from an interface between the substrate base and the cutting tip to a central location on the elongated surface; wherein the longitudinal axis of the substrate base is not co-linear with the central axis of the cutting tip; and characterised in that the elongated surface defining the longitudinal end of the cutting tip is relatively more narrow in a central region thereof than in a radially outer region thereof. a substrate base comprising a substantially cylindrical outer side surface and a longitudinal axis substantially parallel to the substantially cylindrical outer side surface; and a cutting tip comprising: an elongated surface defining a longitudinal end of the cutting tip; a first generally conical surface extending from proximate the substrate base to the elongated surface; a second generally conical surface extending from proximate the substrate base to the elongated surface, the second generally conical surface opposite the first generally conical surface; a first generally flat surface extending between the first generally conical surface, the second generally conical surface, and the elongated surface; a second generally flat surface extending between the first generally conical surface, the second generally conical surface, and the elongated surface, the second generally flat surface opposite the first generally flat surface; and a central axis extending through the cutting tip from an interface between the substrate base and the cutting tip to a central location on the elongated surface; an elongated surface defining a longitudinal end of the cutting tip; a first generally conical surface extending from proximate the substrate base to the elongated surface; a second generally conical surface extending from proximate the substrate base to the elongated surface, the second generally conical surface opposite the first generally conical surface; a first generally flat surface extending between the first generally conical surface, the second generally conical surface, and the elongated surface; a second generally flat surface extending between the first generally conical surface, the second generally conical surface, and the elongated surface, the second generally flat surface opposite the first generally flat surface; and a central axis extending through the cutting tip from an interface between the substrate base and the cutting tip to a central location on the elongated surface; wherein the longitudinal axis of the substrate base is not co-linear with the central axis of the cutting tip; and characterised in that the elongated surface defining the longitudinal end of the cutting tip is relatively more narrow in a central region thereof than in a radially outer region thereof.
