"They are distinctive artifacts, having concave bases with "ears" that sometimes flare outward (Fagan 2005)." ' These tools not only served as points but also as saws and knives. They were often changed in form and function because the hunters would sharpen the points over and over and would eventually turn them into knives then chisels or scrapers. A variant on the Dalton point is the Hardaway point of North Carolina.
