Claim Text:
1. A method of drilling a subterranean bore hole with an earth-boring tool, comprising: engaging subterranean formation material with a cutting element of the earth-boring tool, wherein the cutting element comprises a superabrasive table positioned on a substrate, the cutting element further comprising at least one recessed surface in a cutting face of the superabrasive table, the at least one recessed surface being substantially planar and located, on all sides, radially inward of a cutting edge of the cutting face, the cutting face oriented at a negative rake angle relative to the subterranean formation; extending the cutting element into the subterranean formation material to a depth-of-cut such that a surface of the subterranean formation contacts the cutting element between the cutting edge and the at least one recessed surface; shearing formation cuttings from the subterranean formation by engaging the subterranean formation with the cutting edge; causing the formation cuttings to slide across a portion of the cutting face between the cutting edge and the at least one recessed surface and toward the at least one recessed surface, wherein the portion of the cutting face between the cutting edge and the at least one recessed surface is substantially planar and parallel to the at least one recessed surface; and at least partially inhibiting the formation cuttings from compacting together over the cutting face into cohesive chips by:
