The Forge is a machine that allows your to disassemble most metal items (except bronze).
Metal items can be disassembled and a proportion of the materials used to make the item may be recovered. (Non-metal items require the Workbench)
The item to be disassembled must be in the Inventory and near to the lit Forge. A hammer is also required.
Fuel should be placed inside the Forge (it can also be useful for storage).
NOTE: Wear on the item (check Durability) reduces the amount recovered. For a very worn item, nothing will be recovered and no completion report appears.
