This invention relates to an explosive-containing device for cutting dense material, the device being particularly useful in forced entry situations, e.g. in law enforcement situations or where an immediate entry into a burning building through its wall is required.


A device for controlled demolition, cutting or breaking through a target, which comprises (a) a frangible backing element comprising a layer of a substantially incompressible innocuous material, the layer and the backing element being V-shaped in cross-section thus defining two legs and a cavity therebetween, and (b) an explosive charge having in cross-section a V-shape generally corresponding to the V-shape of the cavity of the backing element, the explosive charge being accommodated and secured in the cavity in mating relationship to said element, (c) ...
