stone grinder

Ski and snowboard tuning machines are most often referred to by the ski tech as a stone grinder.

Not everyone working in a ski or snowboard shop turning screws can operate a stone grinder.

In the wrong hands, a stone grinder can remove fingers, hands and, (if the ski tech has really long hair) the dude's entire head.

I knew this kid who was turning screws in a snowboard shop and destroyed a new snowboard when the customer handed him a green pass and he let go of the board.

The ski shop owner caught his ski tech pouring dirty bong water into the holding tank of his $85,000 stone grinder.

I loved the face my girlfriend made as she tongued my grundel. The amount of pleasure was infinitely excellent.
