This chapter presents and discusses the results of the use-wear analysis of the chipped stone tools from Çatalhöyük. During our work at the site, we did not have time to analyse the chipped stone tools coming from the entire excavation of the East Mound. We decided to fully analyse some well-preserved buildings that could exemplify living units through the Neolithic sequence. We applied this sampling program to Buildings 65, 56, 44 and related middens of the South Area, whose excavation preceded 2009 (and is not reported on here), and Buildings 77, 131, 132 and related middens of the North Area (Spaces 439, 610, 631). We also analysed two deposits (the infill corresponding to Space 623 and the midden corresponding to (23143)) that preceded the construction of Building 131. Regarding the oldest building of the sequence, Building 139, we analysed only the chipped stone tools that came from its infillings (Sp.623). Thus, these chipped stone tools testify to activities not directly connected with B.139.
