Abstract : The patent relates to an underwater cable cutter consisting of a piston accommodated within a cylinder head and isolated from ambient pressure until the cable to be cut releases said pressure. The trigger device is a glass tube sealed at its exposed end and open to a piston chamber at its open end. The piston is connected to a guillotine cutter positioned in the throat of the device such that the cable to be cut when guided into the throat actuates a valve, releasing water under ambient pressure through the open end of the valve to the exposed surface of the piston. Movement of the piston causes the guillotine cutter to sever the cable.
