This 3/4 grooved axe was collected from a multicomponent site in Wyandotte County and donated to the Kansas Historical Society in 1973. While 3/4 grooved axes are frequently recovered from late Archaic sites, their use is not restricted to that time period. They get their name from the hafting groove that encircles 3/4 of the body of the axe. Axes like these are made by pecking a hard stone into a rough shape and then grinding and polishing it into its final state.
