Claim 7:
8. An earth-boring tool, comprising:
a bit body;
a blade extending radially outward from and further extending in a direction parallel to a central longitudinal axis of the bit body, the blade comprising a rotationally leading portion; and
a cutting element secured to the blade proximate the rotationally leading portion of the blade, the cutting element comprising:
a substrate; and
a cutting table secured to the substrate at an interface, the cutting table comprising a superabrasive material, the cutting table comprising:
a first surface including an outer boundary;
a cutting surface at least substantially surrounding the outer boundary of the first surface, the cutting surface oriented at a first angle relative to a longitudinal centerline of the cutting table;
a plurality of first transition surfaces between the cutting surface and an outer lateral edge of the cutting table, each of the plurality of first transition surfaces oriented at a second angle relative to the longitudinal centerline of the cutting table;
a plurality of second transition surfaces between the cutting surface and the outer lateral edge of the cutting table, each of the plurality of second transition surfaces oriented at a third angle relative to the longitudinal centerline of the cutting table, the third angle different than the second angle, the plurality of second transition surfaces positioned in an alternating circumferential sequence with the plurality of first transition surfaces; and
a cutting edge defined by an interface between the cutting surface and each of: the plurality of first transition surfaces; and the plurality of second transition surfaces.
