Victorinox produced the model no. 10 since around 1910/1920. The original Farmer's Knife No. 10 bears little resemblance to the later version. At the beginning of production, the Model No. 10 was a 3-piece pocket knife with a large cutting blade, saw and a special reamer. This is how the model is depicted in the 1922 catalogue. In the 1932 catalog, model No.10 has a corkscrew in place of the punch, but on the back. At the beginning of the production of farmer's knives there were no versions with a corkscrew. Basically, the corkscrew was not necessarily a tool for everyday use in agriculture.
Model No. 10 was produced in 106 mm, 100 mm and 95 mm, but not in 90 mm.
The pocket knife No. 10 originally had a large cutting blade, a saw and a reamer. The later version had a corkscrew on the back and no longer had a reamer. In addition, the saw was not attached to the foot rivet but to the head rivet. There was an optional hanger for this model. Model No. 10 was a 2-layer pocket knife.
Later version: Big cutting blade: 2.5 mm – 2.8 mm; Corkscrew: 2.0mm; Saw: 2.0mm
On the Model No.10 later version, the head rivet held the saw and large cutting blade in place. A center rivet attached the corkscrews to the back. The top tier was that of the large cutting blade, the bottom tier for the saw and corkscrew.
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.
