Abstract
A tool for penetrating a tubular as described. The tool comprises at least one length of linear shaped charge, a carrier adapted to support the/each length of linear shaped charge, and at least one detonation mechanism for detonating the/each length of linear shaped charge. Upon detonation of the/each length of linear shaped charge, a length of material is projected outwardly from the/each length of linear shaped charge towards an internal surface of die tubular, which is thereby penetrated. The at least one length of linear shaped charge is arranged such that, upon detonation, the trajectory of at least one portion of the projected material intersects the trajectory of at least one other portion of projected material at or adjacent the internal surface of the tubular.
