It does sort of resemble a Clovis type Point. But the material is the big give away that it's natural. Though I've seen and actually own some very rough pieces from the northeastern states Schist is not one of them. It will be really difficult to get a good, sharp and sustainable edge on a material as grainy as Schist. It erodes and crumbles very easily. Argilite is one of the crudest materials I believe I've seen from that area but even it sustains a nice sharp edge and shows obvious flaking.
