DR020 Kirk Corner Notch Drill: One of the top drills that I have had in my collection. Measures 4 5/16" x 1 3/16" and is made of a water stained Hornstone Flint. Was recovered in Humphreys County, Tennessee. Comes wit an Overstreet Certificate of Authenticity. Would make a great addition to any collection as a drill this size and quality are EXTREMELY RARE & SUPER FINE!
