Skeleton Key MFG PVC Master Grinders are handmade by Darren Navarrette and team for smoother grinds on pool coping and concrete. Master Grinders are made of PVC just like they were in the old days, so there's no guarantee how long they'll last. Better buy a few. All skateboard trucks are a bit different, so you may have to make minor sanding adjustments to ensure a proper fit.
Match the size of the PVC Master Grinder with the length of your truck hanger when purchasing.
just like the old days
