Abstract: The embodiments of the present invention involve a thinned-skirt shaped-charge liner, a shaped-charge explosive incorporating the liner, and methods for making the liner. The focus of the most preferred embodiment of the present invention is the machining of the skirt portion of the liner to thin that portion to a thickness within about 25% of the thickness of the material around the center of the apex of the liner. The goal is to reduce debris and carrot size without sacrificing performance. In an alternative embodiment of the liner, at least some of the skirt portion of the liner is machined to a rough machine finish, but the mass of the material removed in the machining is insignificant to negligible. The liner of the present invention may be incorporated into a shaped-charge which includes a housing, a shaped-explosive, and the liner, preferably having an opening at the center of the apex of the liner.
