Abstract:
1. Apparatus for cutting through a target, the apparatus comprising: a high-pressure hose, said high-pressure hose at least internally lined substantially with an abrasive resistant material, said abrasive resistant material either a non-rigid abrasive resistant material or a rigid abrasive resistant material; a helix disposed within said high-pressure hose between a jet-nozzle and any significant bend in said high-pressure hose, said helix externally lined throughout the surface area substantially with a first rigid abrasive resistant material; said jet-nozzle associated with said high-pressure hose, said jet-nozzle at least internally lined substantially with a second rigid abrasive resistant material; a coherent abrasive jet-fluid, said coherent abrasive jet-fluid containing a solid abrasive and traveling under pressure through said high-pressure hose, over said helix, and through said jet-nozzle; wherein said abrasive-jet-fluid is used to cut said target.
