Summary:A method of manufacturing a tool component, which is typically a cutting element or a gauge stone in a rotary drill bit, including a layer of ultra-hard abrasive material bonded to a substrate, the layer of ultra-hard abrasive material comprising a pair of opposed end surfaces, an upper surface defined between the end surfaces, and at least one curved and tapered cutting edge defined at the intersection of the respective end surfaces and the upper surface. The respective cutting edges of the tool component and the respective end surfaces leading to the cutting edges are generally wedge-shaped, the upper surface of the layer following generally the same or a similar profile, at least in the region of the cutting edges.
