These 3/4 grooved axes were recovered from the Dickerson site in Atchison County and donated to the Kansas Historical Society in 1878. While 3/4 grooved axes are frequently recovered from late Archaic sites, their use is not restricted to that time period. Axes like these are made by pecking a hard stone, in this case igneous rock, into a rough shape and then grinding and polishing it into its final state. These axes get their name from the hafting groove the encircles 3/4 of its body.
