What are the advantages of iron tools and weapons over stone and copper ones?

Iron tools were more durable. They could withstand the most devastating weather events. As for the stone and copper, they quickly deteriorated. The stone was destroyed by water. It was not as strong as iron. It was not easy to make various household items and weapons from stone. It took a lot of time and physical strength to make the dishes. Copper is not the most durable material. It quickly loses its shape due to mechanical damage. It was convenient to make arrowheads from iron, to make agricultural supplies.
