Artifact is pictured on a centimeter (cm) grid for scale. The beak on this side is lined with quartz crystals.
The Flint Ridge Knap-in, the largest gathering of flint knappers in North America, takes place September 2, 3 and 4, 2011, at Flint Ridge, Glenford, Ohio, just east of Newark and about 1 hour east of Columbus. That's Friday through Sunday of Labor Day weekend. Hope to see you there!
