There was one problem with the new Blacksmith profession. It often happens that a blacksmith makes and sells only new tools and does not buy old ones used for repair. The reason will probably be that the saving of material during repair is not so lucrative and does not give any XP. If there was a recipe for example "repair the iron axe", then the whole process could be automated, the upgrades in the tables could be used to make the repair cheaper and get XP.
I had 15 axes on the white tiger that I couldn't get repaired because no one was buying them.
