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.
Hafting weapons is perhaps best known for its use by humans in prehistory, but it is still practiced by enthusiasts today and the handle of a tool such as an ax is still known as a haft. Many people still practice the hafting techniques by using old-fashioned methods to figure out the best way to attach a handle onto tools, while improving the overall structure and function. Hafting has evolved through the past and the idea can still be seen in the structure of modern day tools such as hammers, axes, and many other hand tools. The evolution of hand tools such as hammers, and axes would be greatly altered had the people of our past failed to invent the idea of hafting. The methods of hafting and the hafting process have also varied and evolved over the years.
There must be some way to attach the artifact to the strap or shaft, and to this end, flanges are often created on one end (the end opposite the cutting edge). Flanges are produced by a process of knapping or grinding the excess stone away, resulting in indentations in the piece.
