a generally polygonal primary body comprising a primary body base, an opposed and similarly-shaped body face with a plurality of primary flank portions extending there between, the plurality of primary flank portions each including a base flank and a top flank adjacent to the base flank, wherein the base flank, respectively, extends away from the primary body base towards the primary body face, and a top flank extends away from the primary body face towards the primary body base to meet at the corresponding base flank at a corresponding middle corner portion;
one or more cutting protrusions, each of the one or more cutting protrusions including a rake face and a tip flat;
