Folding camping stove

A folding camping stove. The folding camping stove may be formed in a clamshell configuration, having two clamshells that fold outward to expose at least two cooking surfaces. A pivot point is provided on the folding camping stove. Each of the clamshells folds about the same pivot point. A fuel train for the clamshells is positioned at the pivot point. A regulator and adaptor assembly is provided for providing gas from a canister to the folding stove. The adaptor guides the gas coming from the regulator and directs it to a fuel train that directs the gas to opposite sides of the folding stove. Each of the clamshells includes a cooking grate. The cooking grates appear symmetrical from a top view, but are slightly offset relative to one another so that the clamshells may be folded inward relative to each other and the grates may nest together.
