The primary objective of this project was to assess the possibilities of microwear analysis for Dutch flint assemblages. Archaeological investigations included those pertaining to form and function (i.e. would it be possible to predict function on the basis of certain morphological characteristics?) and a study of the economic activities carried out at the various sites. Technical objectives encompassed research into the quantification of wear-traces and into the process of patination. Lastly, a reference collection of experimentally-used flint tools was to be started, with special emphasis on those dealing with the processing of fish. This latter material had been under emphasized in previous research-projects and was considered especially important in Dutch (coastal) contexts.
