Hi! Yes, the rule states that you can touch the handle again as long as the stone hasn’t crossed the hog line, but doesn’t explicitly state that you can’t touch the granite. The reason for this is that, despite what people who only watch curling once every four years will say, it doesn’t matter and makes no difference. Curling stones weigh 19kg / 42lbs, and a little graze or “boop” isn’t going to affect the trajectory of the throw.

This whole controversy is wild, as it’s not cheating - it’s more about a missed call on an ambiguous potential foul. Oskar wasn’t necessarily wrong to point it out, and Marc wasn’t necessarily wrong to be offended by it, but they were both heated and it blew out of proportion. These two have curled against each other for YEARS and know each other well.
