Very nice! My grandfather had a HUGE collection of arrowheads, spear points, stone hawk heads, and other native American tools, but almost all of them were stolen shortly after he died. I only have a few, including one of the tiniest arrowheads I've ever seen. I doubt it had a practical purpose. Grandpa always thought it was probably either someone showing off or that it was for a kid's arrow.
Thanks for sharing, it brings back memories of walking along with my grandpa while he found arrowheads. I sucked at it, but he could spot one from the seat of a moving tractor. I remember riding with him while he cultivated and having him stop the tractor, climb down and pick up an arrowhead. Sometimes only a bit of it was showing in the dirt. He would sometimes point at it from the tractor, but I could never see it.
