Made with 3df zephyr free, using 38 photos.
I do not know exactly what type of axehead this is. The closest type I can find is the guilford axe, which is a type found in North Carolina (This piece was found in Champaign county Ohio).
This piece is about 8 inches in length, and is made from a very hard slate (I think).
The mesh is a bit sloppy on one side, due to my terrible lighting skills =/
