Only OK Review by Delane

I was disappointed in this tutorial. I expected to have instruction on how to orient the stone for cutting slabs, or how to pick out rough that had good designs, and that was just not in this article. There is nothing different to cutting Psilomelane (except that it is terribly dirty stone, which is not told) than to cutting any other stone, according to this article. Sorry, not that great.
