    摘要: In one aspect of the present invention, a pick assembly is configured that comprises a pick shank configured to be press fit directly within a bore of a block. The pick shank comprises an inside and outside surface. The pick comprises a pick head opposite the shank. The shank comprises at least one longitudinal recess extending towards the pick head along the shank from a distal end of the shank. The recess allows the shank to resiliently collapse upon insertion into the bore while maintaining a press fit between the bore and the shank.
