Abstract : An explosive device comprising a plurality of serially spaced shaped charges with a flat metal washer at the base of each upper charge which washer is propelled across an annular space, at a known velocity, to impact and thereby initiate the explosive charge driving the next jet in sequence. A metal shield down the center of the charge provides a channel for passage of the jets generated and also, said shield by collapsing under the action of the explosive, propels a particular washer associated therewith and clips off the slow non-penetrating end of each jet, minimizing the required time delay between jets.
