Obsidian flakes

This obsidian flakes makes bautiful arrow heads. This obsidian is normally a natural clear black, sometimes highlighted with reddish streaks. The obsidian spalls are on the small side more for arrow points than knives. (Although you could make a knife from some of the larger pieces.) They can vary from a couple inches to over four inches. They're pre-bagged and sold by the pound, so expect a good mix of the various sizes.
