This arrowhead is in great condition and still sharp. It is likely from the early Hohokam culture. The Hohokam were known to make very fine dart points with serrated edges, in addition to a thin design, which would increase lethality—these are major identifiers.
Their weapon crafting was more sophisticated than surrounding tribes. ?
