The 3/4 grooved axe shown here was donated to the Kansas Historical Society in 1979. It was collected from an archeological site in Doniphan County with multiple occupations. While 3/4 grooved axes are frequently recovered from late Archaic sites, there use is not restricted to that time period. Axes like these are made by pecking a hard stone into a rough shape and then grinding and polishing it into its final state. The groove would have been used to haft the axe to the handle.
