I’ve seen some things like this (the sheath part) on the discord so I thought i’d bring it here.
What if after a long time of exposure to the elements unprotected, metal objects like swords began to rust? This rust could be cleaned off, but if left unchecked, it will wear the sword down and the weapon will have to be repaired. You can make sheaths and maybe scabbards that protect your tools and weapons from rusting. Being inside a backpack will also protect tools. I think only built tools should rust, so an ax head without a handle wont rust.
There was an idea about hidden wrist blades where I suggested that instead of an Assassin’s Creed style gauntlet with a popping blade, there should be a wrist sheath for a dagger.
Probly would be like this but with a more leathery color and less modern (obviously)
