clovis points ranged from a few inches long up to about 9 inches long. None have ever been found hafted- they're an old point type, made roughly 10,ooo years ago. Many people believe they were dart points to be thrown with an atlatl. The larger ones may be to big for that, and could be knives or hand-thrust spear points. All could double as a knife , hafted or unhafted. to haft one you can carve the shaft to fit in the flutes, dull the edges on the last 1/3 of the point , and wrap the entire package with sinew.
