The black arkansas stone israted at approx 1200 grit also. But...it is a very slow cutting stone, not much use for razors unless thats all you have.
I can't explain it, but the grit ratings on these two stones seem to be way off. For Arkansas stones they don't really use the system.

The black Arkansas seems to be about 6K. Ivenever used the Conk, but those who have say it's about in the same range. That is a very useful range, but a little too coarse for a shaving edge. I find that the 8K is about the minimum fineness that's acceptable for shaving, and many guys like it finer.
