That looks rather like a holster for a small pistol. I am still of the nomad camp kitchen equipment opinion. A folded weapon in a quick draw holster seems rather a contradiction unless you throw it unopened at your enemy. Perhaps the holster came from an Afghan Navy Colt.
These interpretations of objects are bound to happen. I and many others have a food masher sold as a club which would also make an effective weapon. In a previous thread about these the kitchen object seemed to be confirmed by the horses mouth so to speak.
