Brush Cleaner

This gadget is for arm to arm combat, for military use. It is a Carbon Dioxide powered punching tool that will dispense its gas load into the recipient of the punch. James Bond would have one of these discreetly hidden for any unexpected fight :) The 25 gram CO2 gas canister is housed in a metal sleeve that is held in the palm of the hand, there is a hollow blade that protrudes out between the middle fingers that dispenses the gas. The finish can be stainless steel, aluminum, cold steel, anything that looks good. The arrow head is interchangeable. The canister is pierced by a hollow pin on the top of the inside vessel. If this could be 3D printed that would be great.
