ID on some arrowheads

[Mudduck]

I mostly find fossils, mainly shark teeth. I met a friend and he hunted arrowheads. Where I am, it is hard to find arrowheads though I did find a broken flint knife that I had posted here in the past.  I traded some shark teeth for some arrowheads and would like to know what I have. Any help would be greatly appreciated.

There are some members from your area (south carolina) that may help. Looks nice!

Not sure on the types, but from the general shape and flaking I would say they are Woodland period and a couple may by Adenas or related types.
Very nice finds! Keep looking and may your luck continue!
