It was not until the invention of bronze or copper-tin alloy, two thousand years later gave a chance to produce relatively permanent tools: axes, hammers, hoes, sickles, knives and weapons: axes, blades of spears, arrowheads and elements of armor.

The invention of bronze, which enabled the production of reusable items, there was a breakthrough and greatly accelerated the development of civilization.
