In one aspect of the present invention, a high-impact resistant tool comprises a superhard material bonded to a substrate at a non-planer interface, the superhard material comprising substantially pointed geometry with a substantially conical portion, the substantially conical portion comprising a tapered side wall with at least two different, contiguous slopes that form an angle greater than 135 degrees, and the thickness from an apex of the superhard material to the interface is greater than the thickness of the substrate.
