Early model tether cars and airplanes were sometimes powered using a CO2 cartridge as a rocket engine. A hole was punched in the small end of the cartridge, letting the compressed gas escape rapidly to produce thrust. This tool has a sharp point that is driven into the end of the cartridge when the spring-loaded trigger is pulled.
