i think people would look way more badass if u could have a sheath 2 put ur 2h in and have it resting on ur back or hip... the same could also be applied for bows..swords..scimmys...arrow quivers..
there could be differnt types of sheaths...starting with basic leather ones...moving up 2 more fancy and decorative ones... and maybe a seperate side invent could be made to show the contents of the quivers/sheath ex: what type and # of arrows can be put into it.. thus saving room in the main inventory for more important items such as food..ess...

there already are arrow quivers. Look on the side of your chaps legs. But to be honest this would not impact the game a whole lot. So I see no point in putting it in. im sure it's be considered before.

just because an update isnt really usefull doesnt mean it cant be put in
its just a cool little addition to the game
and it would make more sense to put away ur weapon into a sheath then into a backpack...

Would look like another addition to treasure trails

I like the idea, but I don't really see it happening.
