Obsidian blade.

I was worried about that big chunk of obsidian, it look like it was segmented and it fractured into five or six chunks but I'll will still be able to get some nice points out of it.

Hey Levi, That's a big and colorful blade. Good Work!
One of my biggest problem in knapping is natural separations in the rock.

Bummer but nice save!
