ABSTRACT The Río Negro is the most important inner fluvial course of the Uruguay Republic. Along its basin, the archaeological record is characterized by flaked stone tools of remarkable workmanship. As part of a long-term experimental program to explore and understand diverse aspects of lithic technologies from the Americas, this paper reports an experiment devoted to reproducing carefully reduced bifacial knives to explore the techniques and stages of manufacture from obtaining the blank to the finished product. Resulting from the experiment a reduction sequence manufacturing model is proposed. It takes into account the techniques, flaking implements, stages of manufacture and other significant data useful to discuss topics related to the traditional technological knowledge involved in the manufacturing process of the studied bifaces. In light of this investigation, various issues related to the reduction trajectory reflected in the archaeological record are discussed.

探索乌拉圭中里奥内格罗盆地双面石材工具的制造：一种实验方法

摘要 Río Negro 是乌拉圭共和国最重要的内河河道。沿着盆地，考古记录的特点是工艺卓越的薄片石器。作为探索和了解美洲石工技术各个方面的长期实验计划的一部分，本文报告了一项致力于复制精心缩小的双面刀具的实验，以探索从获得毛坯到成品的制造技术和阶段. 根据实验结果，提出了一种减少序列制造模型。它考虑了技术、剥落工具、制造阶段和其他重要数据，这些数据有助于讨论与所研究双面制造过程中涉及的传统技术知识相关的主题。
