Wildkat sent me a box of rock, in it was a beautiful chunk of obsidian. My first swing at spalling it resulted in this:
It has some pretty red in it, with the flash on it shows up better.
I started with the long narrow spall and made a little knife blade. Then I took the larger spall and made a point.
I stepped it just a touch and left a little cortex on the blade. It's some good stuff. I think I'll haft the blade to a little deer antler I have and send them both back to Colorado.
