A journeyman told me a while back that the top side (paper side) of a grind rock is far more aggressive, and thus faster, than using the bottom side. I have found that bit of advice to be extremely helpful when I’ve got a lot of grinding to do, but it recently occurred to me that I’ve never done the research to see if there’s a reason why it’s not done widespread. I’ve been doing it for a number of months and never had any issues with doing so, but I figured I’d ask around just to see if anyone else had knowledge to impart.
