history
Victorinox produced model no. 15 between the 1920s and the 1970s. It was a 3-part pocket knife with a large cutting blade, saw, screwdriver and awl.
Compared to other farmer's knives, the Model No. 15 underwent a major change between the 1920's and 1930's. Originally, the No.15 model had a specially shaped reamer or cleat with no sewing hole. This was replaced by a square awl. The shape of the screwdriver also changed, becoming narrower and more delicate. In addition, the saw changed the position of the foot rivet to the head rivet.
Model No. 15 was produced in 3 sizes: 106 mm, 100 mm and 90 mm. There was no size in 95 mm. These 3 sizes were produced in all available variants until the farmer's knives were discontinued.

construction

The awl also moved around the base rivet, dividing the upper layer together with the screwdriver. A center rivet attached the back feathers.
scale material
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.
liners/rivets
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.
