A copper drill is the oldest metal object ever found by researchers in the world. With 4.1 centimeters long, 5mm wide at its base and only 1 mm wide at its tip, in cone form, it was found in the grave of a woman who was about 40 years old at the time of her death, at an archaeological site in Tel Tsaf, near the Jordan River, on the border between Israel and Jordan. Discovered in 1950, the area was a village between 5,100 BC to 4,600 BC. In the late 1970s, scientists began excavations that last until today. On site, the researchers have found items made of obsidian, a volcanic glass with origins in Anatolia or Armenia, as well as shells on the Nile River and ceramics of Syria or Mesopotamia. The artifact found in the excavations was coupled to a wooden handle. Because he was buried in a woman's grave, scientists presume he may have belonged to her. Before the discovery, the first evidence for the use of metal in the ancient East were found in artifacts made of copper found in the cave Nahal Qanah, between 4,500 BC of 3,500 BC. The drill suggests that people in the region began to use metals before 5,100 BC, that is, centuries earlier than scientists thought. The chemical analysis of copper also revealed that it probably came from about 1,000 km away from the Caucasus region. The discovery suggests that people in this area originally imported metal artifacts and only later began to produce them locally. This discovery suggests that the inhabitants of Tel Tsaf exercised or at least had familiarity with advanced technology, metallurgy, hundreds of years before the spread of copper articles from Nahal Qana.
