looks like a big brother of one that I found near Tampa Bay many many years ago. I am not a NA artifact hunter so I dont much about them but it looks like the same material and style. Probably a knife blade though.
Nice finds. A lot of nice points found in that area of Fl. I would guess the big one one the right to be some type of Savannah River. An Archaic to Woodland type. Possible it is a Hamilton but the form is more Savannah River to me.The one the left...hard to tell. It looks River stained though. Possibly a Sarasota type. If it is it would be a Woodland type.
