Like all 75 mm models, Victorinox also developed this model in the 1920s. At the very beginning of production, pocket knives had a slightly different shape. They were significantly wider. A short time later, however, the form changed to that which was retained until the end of the production period in the 1970s.
This model underwent only minor changes over the course of the production period. It wasn't until the late 1950s that there were changes in the shape of the back spring and the tools.
This model had a large and a small cutting blade.
Big blade: 2.2 mm; small blade: 1.25; Rivet: 1.6mm
A symmetrical back spring was installed, which could be used on both sides. As with model no. 50/1, the center rivet is usually invisible. Compared to model no. 50/1, this pocket knife has two additional components. In addition to the small blade, this is the intermediate layer, which on the one hand corrected the difference in material thickness between the two blades and on the other hand served as a soft support for the large cutting blade.
Very different materials were used for the pocket knife scales, from celluloid/ cellidor in one color to imitations and scales made of stainless steel, horn, aluminum or mother-of-pearl.
Liners made of brass, nickel silver or aluminum were used. In the case of aluminum scales, the circuit liners were omitted.
