1. A tool for penetrating a tubular, the tool comprising:

  • at least one length of linear shaped charge,a carrier adapted to support the/each length of linear shaped charge, andat least one detonation mechanism for detonating the/each length of linear shaped charge such that, 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 the tubular, which is thereby penetrated;

    wherein the at least one length of linear shaped charge is arranged such that, upon detonation, a trajectory of at least one portion of the projected material from one length of linear shaped charge intersects a trajectory of at least one other portion of projected material from the same length of linear shaped charge at or adjacent the internal surface of the tubular;

    wherein the carrier is an expandable carrier, adapted to support the/each length of linear shaped charge, the expandable carrier having a central longitudinal axis and including proximal and distal plates longitudinally separated by the/each length of linear shaped charge, the expandable carrier being configured for selective motion between extended and expanded configurations by relative longitudinal motion of the proximal and distal plates.
