Cobham Life Support's cable cutters use an explosive actuation transferred into linear motion to apply high kinetic energy to displace the cutter blade. The moving cutter then severs the cable material and concludes against the anvil.  The cable material is instantaneously released. The straightforward design is applied to a variety of emergency applications including release cables of large antenna, NASA launch vehicles and naval underwater applications.
