Nikola,
Here's the info on the Ski Classics for the wiki.
-----------------------------------
At one time Victorinox offered a series of Classics for U S ski resorts. There are twelve knives in the set, including two for Crested Butte. The resorts range from Killington in Vermont to Heavenly in California, with most being in Colorado. The set appears to date to the mid-1990s, when Victorinox was also producing a variety of other sports-related series such as baseball and football. Occasionally Classics for other ski resorts, such as the translucent red one for Keystone, also show up, but they don't appear to be part of the series.
