Patent ID: 8789468

Claim:
A device for cutting metal, the device comprising a plurality of containers joined together by a connecting harness and attachable to a substrate to be breached, wherein at least one of the plurality of containers includes an ignition control mechanism and wherein a remainder of the plurality of containers each includes reactive material and a reactive material igniter coupled to the ignition control mechanism, wherein the remainder of the plurality of containers including reactive material includes a contact end with a portal configured for directing the firing of the reactive material to the substrate when the device is attached to the substrate and when the reactive material is ignited by the reactive material igniter, and wherein the remainder of the plurality of containers including reactive material are formed of sufficient structural integrity to contain the reactive material sealed therein and sufficiently heat resistant so that a flame resulting from ignition of the reactive material is only transmitted through the portal, wherein the remainder of the plurality of containers including the reactive are arranged with respect to one another so that the flame of the ignited reactive material exiting from their respective portals overlaps.
