CCP7 has a broad chronological sequence that shows the incorporation of lithic blade technology from <em>ca.</em> 7800 cal BP. This is not an isolated phenomenon, as at a regional level this new technology begins to become visible from the middle Holocene, forming an alternative to flake technology. In this study, artifacts made on blades were compared with those manufactured on other types of blanks. In this way, the aim was to evaluate the internal variability of the assemblage, identify manufacturing patterns, and propose possible uses related to the blades subset. The results indicate a certain degree of standardization of the pieces, an efficient use of their edges, a careful selection of raw materials, and specialized designs to perform specific tasks. All this suggests that the adoption of this new technology did not respond so much to a maximization of lithic resources, but rather to a search to optimize the efficiency and versatility of these tools. Thus, this work provides new information on the introduction and development of blade technology in central-southern Patagonia and invites us to consider what motivated its incorporation and/or adoption by the hunter-gatherer groups that inhabited the region from the middle Holocene onwards.</p> Nicolás Maveroff María Teresa Civalero Copyright (c) 2025 Nicolás Maveroff, María Teresa Civalero https://creativecommons.org/licenses/by-nc-sa/4.0 2025-09-15 2025-09-15 31 3 15421 15421 10.34096/arqueologia.t31.n3.15241
