In combining evidence of polish type with other traces of use, Keeley was able to make precise reconstructions of tool functions.

In combining evidence of polish type with other traces of use, Keeley was able to make precise reconstructions of tool functions. His research suggests new hypotheses concerning such Paleolithic problems as inter-assemblage variability, the function of Acheulean hand axes, sidescrapers, and chopper-cores and points the way to future research in Stone Age studies.
