Hi Brandon,
   It looks like a Woodland knife to me.

I have this here quartzite knife. I don't know where it was found in NC. I bought it in a huge collection of different materials. NC lithic materials is just a part of the rocks/materials I have in my collection. I try to research more on the materials found in my area. Quartzite materials is interesting and I would like to know more about them. What age could be estimated on a large piece of quartzite like this?
