what i was able to find was not much. old engravings, couple DARPA players and weapon experts. but basically it seems a harness was rigged around the chest with a hard leather, metal or wooden sleeve that the handle would slip through. with the metal head resting on top of that sleeve and gravity holding it in place. sorta like this...

hey, it's gotta be correct if Gimli did it! tho the ones i saw were more centered on the back, with the weapon straight up & down rather than at an angle.
i realize there'd probably be no correct animation (til someone made one!) for un/sheathing but better a short moment of wtf rather than hours staring at gravity defying goofiness on your back lol. i'm sure the AWESOME hammers and axes in you mods deserve this! i bet there'd be a lot of desire for it. thanks!
