Abstract
A shaped charge explosive device is provided having a front, a rear and an axis of symmetry with the device comprising an explosive charge, a liner lining a front of the explosive charge, the liner having a recess in the form of a groove encircling the axis of symmetry; and the groove arranged to provide an axis of projection for the liner at an angle A relative to the axis of symmetry. A method of cutting a structure is provided comprising the steps of providing the foregoing device, detonating the explosive charge to create a detonation wave; forming the liner into an formed projectile in the shape of an annular ring with the detonation wave; directing the formed projectile towards the structure; and forming an annular ring cut pattern in the structure with the formed projectile.
