That doesn't sound right, if they use american it would be the other way around I think. And thats confusing because if people are saying it should be so sharp at such and such grit, what grit are they talking about? I'm only used to Japanese grit because I've only ever used Japanese stones. At first I thought all waterstones used Japanese grit and American grit was for sand paper.

edit
I did my own research and nortons use japanese grit
