Together with a few other models, model no. 6 was one of the first farmer's knives that Victorinox ever developed and produced. In addition to the large cutting blade, the No. 6 model had a hooked blade. Originally the size was 112 mm. Later, 4 smaller sizes were produced between 106mm and 90mm, while the 112mm variant was no longer produced.
The first models still had iron jaws, this was the so-called «Courante» version. The finer versions had nickel silver bolsters.
For a long time, model no. 6 was offered in all 4 sizes and all available variants, but from the 1964 catalog no longer in the smallest size of 90 mm. The changes in this model were only minor, or affected changes that affected the entire series of farmer's knives: Introduction of variants in rust-resistant steel; other cheeks from 3 narrow decorative grooves to 2 narrow and 1 wide decorative grooves; switch from black fiber scales to red ; Etc.
Pocket knife No. 6 had a large cutting blade and a hooked or curved blade. There was an optional hanger for this model. Model No. 6 was a 1-layer pocket knife.
Big cutting blade: 2.4 mm – 2.8 mm; Hook Blade: 1.9mm - 2.3mm
In model no. 6, the head rivet held the large cutting blade in place, and the foot rivet held the hooked blade. To compensate for the difference in the material thickness of the two blades, an intermediate layer was used for the base rivet. A center rivet attached the back spring.
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. The high-quality, called "fine version", used rivets and liners made of brass as well as jaws made of nickel silver and rust-resistant steel for the tools, if this was already available.
