Thanks Jamie, I do like the color but not the grain part of the stone. I would like to find flint in the creek that is smooth like the tip of the larger arrowhead in the picture. I guess if you lived 1000 years ago you would know what type of flint and kind of arrowhead was best made from what material. Heat treating the stone made the larger flakes thinner and longer and required less force from the bopper to remove. Also I noticed it was less likely to step or hinge when striking the point.
