There are most popular Victorinox models, sometimes referred as “big” in comparison with 58mm knives which are “small”. The most popular Victorinox models as Spartan, Camper, Climber, Fisherman, and others come in 91mm size.
In dropping menu under Swiss Army Knives / Victorinox 91mm you may find 91mm models from my collection. I hope you will enjoy it.
