ABSTRACT OF THE DISCLOSURE The application discloses improvements in hollow charges for linear cutting or demolition purposes wherein a bar formed from a composite of explosive material and a first pliant material has a V-shaped groove with a liner formed from a composite of particulate metal and a second pliant material. The metal may be copper and preferably the first and second pliant materials include the same constituents. The charge may include a casing having a spacing portion having an engagement surface for presentation to a work surface, which engagement surface is parallel to the outer edges of the liner and spaced therefrom to maintain an optimum stand-off distance. The casing may further include a groove filling portion of low density material which may be integrally constructed with the casing from a flexible material such as expanded polyethylene.
