Here is a replica that I did of an artifact. The owner indicated he found the projectile in the Columbia River Gorge near Cascade Locks,OR. The original was made of a dark reddish brown rock that looked like jasper. My replica is made from mahogony obsidian and is identical in length (2.5 inch) and thickness, but just tiny bit wider than the original. However, the original was very worn on the edges. I figured the original was a little wider when the edges were sharp. Since it is as easy design, I tried to get nice oblique flakes. The flake scars are not perfectly lined up to center line, but are OK for me. I am not an Archeaologist, but this seems to match the leaf shaped points used on spears or darts by the old Cordilleran Culture or the Cascade phase in the Pacific NW. The original may date to between 5500 - 9000 BC.
