Weapons on the Wall
It’s immature, at best (and scary, at worst.) Put them away—for good. If someone new visits you, they will be really scared if you have a weapon on the wall. You are not a child to put your toys random.
If you are often visited, then your guests are really scared of these odious things! If you ask me, if I have to go in a weapon decorated place, I would expect every moment to be attacked.
