Weapon Repair Orders. Simple enough. Adventurer wants a weapon repaired, you heat the metal in the forge and then you hand it back.
To have a repair mechanism that fits the style of gameplay, you'd want to have a process such as:
- Disassemble their weapon on the anvil
- Move the blade to the forge, heat it
- Bring the blade back to the anvil and hit it a couple times
- Reassemble the weapon and hand it back to the customer
Or for simple replacement part style repair:
- Disassemble their weapon on the anvil
- Replace their broken part (handle, blade, guard) with a new one from your supply
- Hand the repaired item back to the customer
