Dan explained that stone grinding can get very technical, to the point where the diamond chips in the machine can be programmed to apply various patterns to the ski base. In the world of competitive ski racing, ski engineers experiment with different patterns to find the best pattern for snow conditions and type of race, i.e. slalom, giant slalom, etc.
Jack and Dan's Tip: A good stone grinding can be beneficial because the moisture content of the snow creates suction on a flat ski. A flat ski is held onto the snow, but a good stone grinding allows more natural movement.
