The Victorinox Matterhorn Swiss Army knife is a rare, retired, standard sized 91mm / 3 1/2" Swiss Army knife, with pliers, a serrated blade and a basic assortment of other tools. This is part of the "mountain" series of serrated Victorinox knives. Victorinox also produced a Climber knife with a printed image of the Matterhorn on the front scales. That knife also shared this model name.
