I just got one of the "Natural Polishing Stones" from China that Woodcraft carries. They claim it is 12,000 grit plus. Here are some observations based on using it on a few tools.
The stone is pretty dense, black in color a few white veins, and while hard, is softer than some arkansas stones I have used. Not sure what specific kind of stone it is.
I think it is at least on par with my 8000 grit Norton stone. I think it cuts bit harder, but the Norton is a bit soft and dishes out quickly.
I find it is good for honing micro bevels, as they are hard to strop so it is good to hone them on the finest stone available. Also I find that my Norton 8000 grit stone is a bit soft and tends to give inconsistent results.
I used it to hone two LN plane blades today. After a quick strop they both left some nice bald spots on my arms :cool:
For 29 bucks it is a good deal.
