  • Patent number: 4222329
    Abstract: An underwater cutting device which utilizes a W shaped liner to separate a inear explosive charge from a watertight standoff volume. The liner is fabricated by bending a single metal plate. A V shaped hood is affixed to the outer edges of the W shaped liner and the charge is contained between the hood and the liner. A metal box having the shape of a flat bottomed U is welded to the points of the depression in the W and in cooperation with end pieces, provides the watertight standoff volume.
