#956 has to be a combination tool for muzzle loading rifles and muskets. The 'corkscrew' would be used for pulling patches lost at the bottom of the bore. The screwdriver end for tightening the jaws holding the flint. The tiny hammer for knapping (sharpening) flints. The pointy wire for clearing touch holes. The jaws also could be used for sharpening flints. And there are a couple features I'm not sure about. I've never seen a combo tool for flint muzzle loaders quite like that one. No doubt, it came from a cased set of high end guns.
