So what was the purpose of these tiny points? I’ve always heard them referred to as bird points. I would think a blunt would have been sufficient for small game instead of knapping points.
They used them as arrowheads.
Anything they killed with a bow and arrow. Bison, deer, elk, men... etc.
The "arrowhead" was a small point like that.
The bigger points were dart points, and used not with a bow, but an atlatl... A spear thrower.
Those size points are known as dart points, or spear points.
