I'm not sure if this is known or not.
I removed my worn duel axes and went to harnquist to purchase two new ones.
I didn't sell my worn axes, only removed them into my inventory slots.
After purchasing my two new axes, I come to discover that the two new axes took on
the worn axes durability.
This is obviously a bug, or I would hope that it is considered a bug since I really can't see why
two brand new axes would be effected by worn axes.
Thanks
