history
Like all models in 75 mm, Victorinox also developed model no. 53 in the 1920s. It was the only model in the series with a corkscrew. The production of this model was discontinued around 1950, while the pocket knives continued with the same functional parts in the size 84 mm.
functional parts
In addition to a large and a small cutting blade, the model had a corkscrew on the back. The corkscrew has four turns and a decorative groove. In the 84 mm size, the corkscrew had five turns. This model did not come with a toothpick and tweezers.
material thickness
Big blade: 2.5 mm; small blade: 1.5 mm; 2.5mm. The material thickness of model no. 53 is greater than that of the other models at 75 mm.
construction
The No. 53 model featured a single back spring. The three visible rivets each fix a functional part, while the back spring is attached by a rivet located under the scales.
scale material
Mainly mother-of-pearl and horn were used as the scale material. According to an older catalog (cf. cat. 1936), there were also variants with engine-turned steel, tortoiseshell and celluloid/ cellidor in imitation mother-of-pearl. This shows the immense range of models and variants of the 75 mm series. There may have been a few standard designs and many rarely requested combinations could be ordered from a certain quantity.
liners
The liners, as well as the rivets and the spacer, are made of nickel silver.
