Vintage & Rare Victorinox 91mm (3.5 inch) Swiss Army Knives

This list covers rare, collectible and vintage 91mm standard-size Victorinox Swiss Army knives. These knives are scarce, and often in high demand! We have to work hard to find them, so they are much costlier than new or recently retired models. If you want something more reasonable, current 91mm knives and recently retired knives are listed separately.
