Model No. 9 first appears in the 1922 Victorinox catalogue. Model No. 9 was a 2-layer pocket knife with 3 tools. In addition to the large cutting blade, the No. 9 model had a saw and a hook blade.
As with many peasant knives, the saw was originally attached to the foot rivet on model no. 9. From the 1930s it was on the head rivet.
Model No. 9 was produced in all possible and available sizes and variants until the end of the production period.
Pocket knife No.9 had a large cutting blade, a saw, and a hooked blade. There was an optional hanger for this model. Model No. 9 was a 2-layer pocket knife.
Big cutting blade: 2.5 mm – 2.8 mm; hooked blade: 2.0 mm; Saw: 2.0mm
On model No.9, the head rivet held the saw and large cutting blade in place. A center rivet attached the back spring. The top tier was that of the saw, the bottom tier for the large cutting blade and hook blade. The large cutting blade and saw could be opened from the front, the hooked blade from the back. This arrangement was different from, for example, the Model No. 8 which was also a 3-piece pocket knife but had the saw mounted on the lower tier.
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.
