I've been emailing Boarrancher for a while now getting help with my flint knapping, he is a master craftsman at it don't ya know. As a thanks for all his help I sent him a home made knife, nothing fancy just a small knock around patch knife.
Well imagine my surprise when I opened the mail and found this in there.

It's rainbow obsidian, if you look close you can see a line down the middle that is actually a color inside the rock. This piece is so thin on the edges that you can read a piece of paper through it if you hold it up in front of a light. You have MAD SKILLS brother.
If you ever get a chance to pick up one of his stone knife that are offered for sale from time to time you should do it. You won't find a better example of craftsmanship anywhere.
Thanks Joe, I will remember this.
