Since I will receive my Hattori HD in a few days, I am planning to get the Apex Edgepro sharpener.

Problem is that they are talking about stones (600, 320, 220, 180 & 120 grits) with a different classification than what we usually read here (1000, 4000...).

Question is : how do they compare ? Is the 600 grits similar to 8000 for a japanese wet stone ?

Some explanation are needed [img]/ubbthreads/images/graemlins/confused.gif[/img]

Thanks for your help !!
