Demi Fuck, When starting out, you are usually given a limited number of weapons and tools. These help fortify you. When you run out of them, you can either restock them with materials found around the map (the same way you replenish your weapons) or re-equip yourself with new ones. The trick is to always have some available for you, or else you risk running out while you are questing or fighting. This is why it is advised that you collect more weapons and tools as you progress through the game.
