It's amazing that some here imagine that diamond can barely scratch granite for some silly reason but yet so many of the videos that follow that don't have any problem doing so....... Why is it that granite should be immune to quartz abrasive or for that matter a harder rock hitting it? I would love to see a video of any fringe author of the “Menagerie of Lost Advanci-nesses”, up and coming or otherwise, go at their rather expensive granite countertops with quartz sand (and I don’t mean the fine stuff that will polish) or a cobble of basalt with just a fraction of the vigor they spend insinuating no harm a gon'a be done.
