[origin: WO2018162442A1] A strike tip for a pick tool is provided. The strike tip comprises a strike structure comprising a super-hard material and a substrate comprising cemented carbide material, the substrate being joined to the strike structure at an interface. The strike tip has rotational symmetry about a main central axis. The strike structure has a planar apex area and, on a plane on which the main central axis lies, a convex curved side wall extends between the planar apex area and the substrate.
