Abstract

The application discloses improvements in hollow charges for linear cutting or demolition purposes wherein a bar (1) formed from a composite of explosive material and a first pliant material has a V-shaped groove (2) with a liner (5) 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 (6) having a spacing portion (7, 8) having an engagement surface (12) for presentation to a work surface (10), which engagement surface is parallel to the outer edges (9) of the liner (5) and spaced therefrom to maintain an optimum stand-off distance. The casing may further include a groove filling portion (17) of low density material which may be integrally constructed with the casing from a flexible material such as expanded polyethylene,
