This Stonehenge hammerstone is absolutely immense, yet it does not have any marks or shapes to suggest that it was hafted and how it was used remains conjectural. It is well worn from use, with a number of broad facets around its most bulbous half. None of the other curated hammerstones have any handle evidence, and there is a long range from hand-held size all the way up to this massive example. Despite many years of archaeological study of stone tools, aspects of Neolithic and early Bronze Age technology are yet to be understood, as is the significance of worked and un-worked stones being used in stone circles and other monuments within the WHS.
