For a few years, Victorinox offered a version of the Cadet Swiss Army knife with a copper coating on the ribbed aluminum alox scales. They never offered this finish on any other knives, and discontinued the Copper Cadet after a couple of years.

This unique finish is very attractive and unusual. The copper color wears fairly well, but it will eventually wear through from "pocket wear", particularly if you carry coins, keys or other metal objects in the same pocket. Since this knife is collectible and moderately expensive, you might want to carry it in a protective case, to maximize the lifetime of the finish.
