The Neolithic period was the last stage of Stone Age and is characterized by the use of ground or polished stone weapons, tools and implements.The Neolithic tools & weapons: axes and hammers, adzes and chisels, knives and scrapers, sickle and hoe were used for cereal cultivation and animal domestication.The Chalcolithic (or Eneolithic) era marks a transition period to the Bronze Age with the introduction of Bronze metallurgy. 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.
