In Europe the arrival of bronze tools and weapons did not play a noticeable role in production for household or military craft. Stone still was used for implements or battle weapons. Many of them were multi-purpose tools that could be used as hoes, working axes, adzes, chisels and battle axes depending of the method of fastening the haft. P. V.
