The 91mm Modeler is a discontinued knife with an uncommon combination of tools. Its key features are the magnifier, inline Phillips screwdriver, scissors and metal saw/file. Combined with two knife blades, can opener, cap lifter, awl and corkscrew this might just be one of the most useful of all Swiss Army Knifes!
The scissors have the adjustable screw pivot, which Victorinox stopped using in 1991. Therefore, this knife is at least 25 years old! I’m very happy to have found one completely new in box!
