Those notched pieces are nice they are rare up here in Ohio ive only found 1 broken one, nice finds man.Those Pencil Drills are one of the more common types of drills in the areas I hunt. Micro drills and T-Drills are also to be found around here. The notched types are the rarest, I've found less than ten in 20 or more years of hunting.
Some personal finds from western Va. and southeast Wv.
