Description |
English: Metal point. Metal projectile points like this one, that archeologists unearthed at Fort Union, were introduced to American Indians during the fur trade. It’s triangular shape and rectangular stem, called a tang, are similar to the knapped flint points most people picture when thinking about arrowheads. Unlike flint arrowheads, metal points could be mass produced.
