In 1980 Montana of Switzerland imported 3 "Monty" stone grinders into the U.S. and we purchased the 1st one to be installed into a retail shop. Since that time we have prided ourselves on being the "tip of the spear" as it relates to ski tuning in the Midwest and beyond; upgrading our machinery 6 other times. Now for the 7th time we have raised the bar again with the installation of our new Montana Crystal Rock ski tuning system. For more information please see the video below.
