Similar to the other models in 75 mm, Victorinox also developed the No. 55 model in the 1920s. It was produced until around the early 1950's when production was discontinued.
In addition to a large and a small cutting blade, this model has scissors and a nail file on the back. Compared to model no. 52, the nail file is very wide on the back and covers both layers.
In mother-of-pearl and horn there was also the option of toothpicks and tweezers.
Big blade: 2.3 mm; small blade: 1.2 mm (1.6 mm with old version); Scissors: 2.3mm; Nail file: 5.0 mm (5.5 mm old version).
The first position is identical to that of model no. 52. Large and small cutting blades rotate on a back spring, which is branched on one side. The second back spring is of a similar shape, with the same branching. Due to its wide shape, the nail file needs both back springs for tension.
Horn, mother-of-pearl, engine-turned steel, celluloid/ cellidor in imitation mother-of-pearl and tortoise scale were used as scale material, but not the black oxidized steel used for models no. 50, no. 52, no. 53 and no. 54.
The liners, rivets and the intermediate layer are made of nickel silver.
