1. A method of forming a cutting device, comprising:
- arranging a plurality of individual polycrystalline cutting elements in an uncured organic material, each of the plurality of individual polycrystalline cutting elements having a substantially matching, wedge-shaped geometric configuration and a longitudinal axis extending from a base of the wedge-shaped geometric configuration toward an apex of the wedge-shaped geometric configuration;
orienting at least some of the wedge-shaped cutting elements such that a longitudinal axis of each of the at least some cutting elements is aligned along, and is collinear with, a radius of the cutting device, and a wider portion of each of the at least some cutting elements is disposed nearer an outer perimeter of the cutting device than is a narrower portion of each of the at least some cutting elements; and
curing the organic material to form a solidified organic material layer, such that each of the plurality of individual polycrystalline cutting elements is secured therein.

11. A method of forming a cutting device, comprising:
-
obtaining a disk of polycrystalline superhard material; dividing the disk into a plurality of cutting elements, each of the cutting elements being a substantially equal portion of the disk and each having a substantially matching wedge-shaped geometric configuration and a longitudinal axis extending from a base of the wedge-shaped geometric configuration toward an apex of the wedge-shaped geometric configuration, the substantially equal portions of the disk collectively providing a surface area substantially the same as a surface area of the disk prior to division of the disk; radially arranging the plurality of individual polycrystalline cutting elements in an uncured organic material such that the longitudinal axis of each of the individual polycrystalline cutting elements is aligned along and is collinear with a radius of the cutting device; and curing the organic material to form a solidified organic material layer, such that each of the plurality of individual polycrystalline cutting elements are secured to the cutting device. - View Dependent Claims (12, 13, 14, 15)
