Title: Black concrete
Post by: Tower on June 01, 2011, 06:22:59 pm

I hadn't posted much lately been covered up at work. I had this piece of something that came from the Colorado river in central TX. I worked it raw & beat up some good boppers. This stuff is like concrete, I had to hit it like I live hard & fast. I thinned it the best I could ,it hinges in a bad way.I sacrificed my width trying to remove the hinges. Here are a few pics of it.

Nice blade, that stuff looks like Ryolite. I read that there was some out that way.

Good one Tower! Hey, I found a bunch of grey/green tabs that work about like that.

If that's anything like the black chert I have, it heat treats well.

That's a nice piece. It's amazing how much rock is removed to make a point.
