Bay scrapers have been stone tools known since the Moustérien , but they were more common in the Neolithic Age . They are flint chips that have one or two indentations at the end or on the side.
Bay scrapers were used to round or smooth wooden shafts. Rods intended for braiding were also debarked and smoothed with bay scrapers before they were divided and processed.
