An earth-boring tool, comprising: a body; and a plurality of cutting elements attached to the body, each cutting element of the plurality of cutting elements comprising: a substantially cylindrical substrate base; and a cutting tip comprising: a first generally conical surface extending from proximate the substrate base to a longitudinal end of the cutting tip; a second generally conical surface extending from proximate the substrate base to the longitudinal end of the cutting tip, the second generally conical surface opposite the first generally conical surface relative to a longitudinal axis of the cutting tip; a first flank surface extending from proximate the substrate base to the longitudinal end of the cutting tip and extending between the first generally conical surface and the second generally conical surface; and a second flank surface extending from proximate the substrate base to the longitudinal end of the cutting tip and extending between the first generally conical surface and the second generally conical surface, the second flank surface opposite the first flank surface relative to a longitudinal axis of the cutting tip; wherein at least one cutting element of the plurality of cutting elements is oriented relative to the body such that the cutting tip of the at least one cutting element is back raked and configured to initially engage a formation to be bored by the earth-boring tool with one of the first generally conical surface and the second generally conical surface of the at least one cutting element; characterised in that an elongated surface comprising a central region and radially outer regions defines the longitudinal end of the cutting tip, and is relatively more narrow in the central region thereof than in the radially outer regions thereof. a body;
