This article describes a bison rib bone foreshaft from the Blackwater Draw site, New Mexico. The object was recovered by James Hester in 1963, during the excavation of locality 4, and it was subsequently cataloged as a modified bone tool but not recognized as a hafting element. It is currently held in the Blackwater Draw Museum collections. This analysis provides a detailed description of the artifact's features and establishes its provenience from a Folsom context. A survey of known Paleoindigenous hafting implements and a discussion of theoretical Folsom foreshaft designs serve to reinforce the classification of the tool as a component of the Folsom weapon delivery system. The tool was likely broken during use and later recycled as a pressure flaker or as a polishing instrument. With the help of 3D imagery, a reconstructed model was printed and fitted with large and small Folsom points to test ideas borrowed from the theoretical literature on Folsom foreshaft design.

本文描述了来自新墨西哥州黑水抽矿场的野牛肋骨前轴。詹姆斯·赫斯特 (James Hester) 于 1963 年在地点 4 的挖掘过程中发现了该物体，随后将其归类为改良骨工具，但并未被识别为轴系元件。目前它被黑水绘图博物馆收藏。该分析提供了该文物特征的详细描述，并从福尔瑟姆的背景中确定了其出处。对已知古土著轴工具的调查和对福尔瑟姆前轴理论设计的讨论有助于加强该工具作为福尔瑟姆武器运载系统组件的分类。该工具可能在使用过程中损坏，后来作为压力刨片机或抛光工具回收。在 3D 图像的帮助下，打印了一个重建模型，并安装了大大小小的 Folsom 点，以测试从 Folsom 前轴设计理论文献中借鉴的想法。
