I know they are broken in places but they sure look cool. What is the
smallest one called and its use? It doesnt seem to be broken in any

I'd say you have another nice Hell Gap point, used on the end of spear or dart.  Thrown from the atlatl.  Two of the other ones are a little dinged up, but you can't get much better paleo than that!

Which one are you referring to?

The one you are asking about in your hand is the Hell Gap.  But, they are all spears/ darts for atlatl's!
