Raddatz points are arrow and spearhead tips used for hunting between Native American tribes. Though it is difficult to attach an exact date to the production of these artifacts, they appear to have been made from 6000 to 3000 B.C. They have been discovered in the Midwest, especially Illinois, Michigan and Wisconsin. The name of the point came from the Raddatz Rock Shelter in south-central Wisconsin.
Raddatz points are known for being side-notched near the base of the spearhead. These notches are U-shaped and were used for hafting the point on an arrow or spear shaft. The points range in length from 1 1/2 to 3 inches, and are made from local Midwest chert. To harden the stone, it was common for the points to be heat treated.
