Nice drill Larson. Have you typed the point it was made from?
Looks like a Prarrie side notch.. 800-1300 BP.
There was probably several real nice Bone fish hooks made with the help of that piece.
I'm sure they start out sharp. With all the bone awls and perferators he finds seems bone was the choice material for that task. That's a great example of a classic Hafted drill. JMO.
