Not to be confused with the Workbench.
The Repair Bench was an item used to repair broken or badly damaged Tools, Weapons and Armor. In order to craft, players needed 12 Stones, 60 Wood, 50 Metal Fragments and 6 Low Grade Fuel. After repairing an item, it's maximum condition is lowered, causing it to last shorter after each repair. An item is repaired using the same resources used to craft it. Repairing items, up to a point, is cheaper than making new items.
