Hafting is a process by which an artifact, often bone, metal, or stone, is attached to a haft (handle or strap). This makes the artifact more useful by allowing it to be shot (arrow), thrown (spear), or used with more effective leverage (axe or hammer). When constructed properly, hafting can tremendously improve a weapon's damage and range. It is estimated that hafted weapons were most common during the Upper Paleolithic and Middle Paleolithic. Hafting was a significant milestone in the history of technology. It was one of the first tools where hominins took separate elements and united them into a single tool increasing the efficiency and use of it. The development of hafting was considered a significant milestone of humans by archaeologists. It was not only a significant improvement in the technology at the time but archaeologists also believed that hafting shows the progression and development of the human mind and shows the path toward a world of complex tool making of the past. The idea of assembling two different kinds of materials into one object that improves the functioning of the tool overall shows the mental capacity of the people of that time and gives archaeologist a better understanding of the progression of human life.
