Let’s get this thread back on track, ignore the nay sayer and talk about rocks!
As a rock hound I find this thread pretty cool. The way they are shaping the hones leads me to believe that it is a very soft stone. I was just in Oaxaca and did not even think to ask about natural hones. Of course my Spanish is so weak I’m not sure I would have been able to ask the right people the right questions.
I was just testing my local finds yesterday. I love rockhounding.
