Indian artifact arrowhead authentic lot of 4 black Gary knives Oklahoma

Description

Up for auction is a lot of 4 black Gary knives found in Oklahoma. These range from 2 1/2 - 2 3/4 inches.  Material has me stumped. Quartzite/rhyolite type material.
All I have on this collection is that it was found in Oklahoma.  There is a tiny amount of glue residue on a couple from being glued to a board. I thought I got it all but I can see a little in pics. Should soak off.
Please look at all pics closely as the size and most angles are present.
$$$$$ I ask that payment is made within 3 days of closing.$$$$$
