With a bit of twicking, this could work. A higher smithing means better weapons, this would greatly help mine/smith skillers. (Me being a skiller in training, being a bit bias) After a lot of use, the weapon would fatigue. But if you can repair it at a anvil, with at least half the required smithing. if you have the smith skill to make it, you can make it in a slightly better quality then you made it, but only once per level. After five levels, you can make it at the best condition possible.
