Norinco .22 Pistol Combat Knife,For use by Chinese Special Forces, this neat little combat knife also doubles as a four shot .22 long rifle pistol.  The knife has four chambers/barrels in the grip, with a trigger protruding from it.  To load the pistol one unscrews the back which exposes the breech.  A rotary safety catch is located forward of the breech, and screwing it clockwise arms the weapon.  When unloading one unscrews the cap, but the empty cartridges will be ejected with a pull of the trigger. -- source link
