Hmmm....having said that, not that it will happen, but for this one: The forge is losing its tool slots for the anvil, crucible, and die set, I'd like to see you have to upgrade those (and your experience in the field) to depend on the item quality.
So put a rock in the slot and to hammer on a rock you can only get a blade 30% sharp.
Put some scrap metal in there and you can get it up to 60%
Put the anvil in and it's 60 - 100% (or something like that).
And then have a limiter based on your experience, or something like that?
