Victorinox produced model no. 13 between the 1920s and the 1970s. It was a 3-part pocket knife with a large cutting blade, a saw and a small cutting blade.
Model No. 13 was offered in all sorts of sizes and variations, with scales made of horn or fever, with tools made of carbon steel or stainless steel. This model underwent only minor changes. Between 1920 and 1930 the saw changed its position from the foot to the head rivet. The small cutting blade never changed shape.
Pocket knife No.13 had a large cutting blade, a saw, and a small cutting blade. There was an optional hanger for this model. Model No. 13 was a 2-layer pocket knife.
Big cutting blade: 2.3 mm – 2.8 mm; small cutting blade: 2.0 mm; Saw: 2.0mm
On model No.13, the saw and large cutting blade were attached to the head rivet, only the very original version still had the saw attached to the foot rivet. The small cutting blade turned around the foot rivet. A center rivet attached the back feathers. In model no. 13, the small and large cutting blades share one layer.
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.
