Starting 15,000 years ago the main weapons of choice were made of rock. These rocks were chipped to form arrows and spears. Then about 7000B.C. copper was discovered. This made weapons stronger and it was still to soft so they combined copper with tin to make bronze about 2800 B.C. which was much harder and better for combat. This lead to the development of primitive swords and axes. The use of bronze was also very flexible and anyone who owned a small furnace could make any weapon they desired. The first type of mass production.
