As it is, an item the degrades past the 'crumbling' stage without being repaired disappears entirely, right?
Well, would it be possible that instead of just ceasing to exist, it returns to being the materials it's made out of?
For example, if a shovel is sitting in storage for so long that it degrades entirely, instead of nothing being there, there will be an amount of iron (or whatever shovels are made of).
It doesn't necessarily have to be the full amount of materials either... An item that originally needed 300 grams of steel and 50 leather (just picking random numbers, here), if degraded, would end up as 200 grams of steel and 35 grams of leather, or something like that. I'm not too concerned with the amount lost, as long as there is at least SOMETHING left.
