How does meta crafting work? does it work only for smithers and those who work on an anvil? do they need tools like an anvil, hammer, or some place to work or does it work like they have only just their hands and grab like say an apple and a pencil put it together to make a car or something similar? I need to understand. Or do say like they get just an hammer and some object like a crayon or pencil hit it once with hammer and it turns into a laptop?
