Changes to copper tools, currently they are not worth crafting since the gap between stone to copper and copper to iron is too small, copper tools also are closer of use to stone tools than to iron, because copper tools can mine the same blocks as stone and the sword does the same damage. In my oppinion its better craft iron tools after stone since iron is not that rare. Solution? Make copper tools not an in-between tier since its way to small of a step, make them like gold unique in some way that dosent interfere with the tool progression.
