Nothing is known about models no. 20 – no. 24. These no longer appear in the 1922 catalogue. Either the production of these models was stopped, or the quantity produced was too small to mention them in the catalogues. There were some models of peasant knives that were never shown in a catalog.
The peasant knife with the number 25 appears for the first time in 1922. At that time it was only produced in one size. From the 1930's until the end of production the No. 19 model was made in 3 sizes, 106 mm, 100 mm and 95 mm. In the 1922 catalog, the Model No.19 was the only one that had the saw attached to the head rivet rather than the foot rivet. As one of the few peasant knives, the construction remained the same throughout the production period.
The No.25 model featured a large cutting blade, a saw, an awl, and a corkscrew on the back. The additional bail was available as an option for the model.
Big cutting blade: 2.5 mm – 2.8 mm; Awl: 2.0 mm; Corkscrew: 2.0mm; Saw: 2.0mm
In model No.25, the large cutting blade and saw were attached to the head rivet, the pocket awl to the foot rivet, and the center rivet held the corkscrew in place. The upper layer consisted of a large cutting blade and pocket awl, the lower layer of a saw and corkscrew. Model No. 25 was a 2-layer pocket knife.
Victorinox originally used black fiber scales as the material for this pocket knife, later also class I and II horn and red fiber instead of black fiber.
The rivets and liners were made of steel or brass, the jaws of steel or nickel silver, depending on the version. In the case of the high-quality, so-called "fine version", rivets and liners made of brass and jaws made of nickel silver were used, and rust-resistant steel was used for the tools, if this was already available.
