Oldest Stone-Tipped Spear Points (2 of 3) (image) University of Toronto Caption These are examples of experimental hafted points from a University of Toronto-led study. Points were hafted to wooden dowels using Acacia resin and sinew and then thrust into a springbok carcass target using a calibrated crossbow. The Kathu Pan 1 archaeological points show a similar pattern of edge damage to these experimental points.
