Abstract

A pick tool (100) comprising a strike member (110) non-moveably attached to a pick body (120), the strike member comprising a strike structure. The strike structure comprises super-hard material and defines a planar strike surface (112), the strike surface defining a cutting edge (114) that includes an apex (115) in the plane of the strike surface (112). The thickness of at least a proximate volume (107) of the strike structure adjacent the cutting edge (114) is at least about 2 millimeters.
