Jamie, the rootbeer colored stuff is Knife River flint from North Dakota. Good job on those. That rhyolite is great for hunting points, gets sharp and won't hardly break. Ancient Chinese secret for the hangnails: heat it up and rub beeswax on it or hit it with a shot of Armor-all. No more hangnails.
Nice chippin', Outbackbob. Shannon, I think yours look better than mine.
