An assembly is disclosed including a holder block, a cutting pick, and an optional hollow sleeve, wherein the shank of the cutting pick is inserted into the holder block or, where present, into the hollow sleeve. When assembled, surfaces of the components meet at an interface. At least one of the first interface and the second interface includes one or more sets of wear elements including cemented carbide bodies press fit into recesses in the forwardly oriented surfaces meeting at the interfaces. The wear elements mitigate direct contact between the opposing surfaces of the components at the interfaces and prevents excessive wear from repetitive impact because the harder wear elements, e.g., cemented carbide, are contact points between the opposing surfaces of the components at the interfaces. A machine incorporating the assembly and a method of manufacturing the assembly are also disclosed, particularly a machine for mining, excavating, tunneling, road planing and/or construction.
