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. <EOS>
