Model No.3 was one of 6 models featured in the 1909 catalogue. It was a 1-layer pocket knife with 2 tools, a large cutting blade and a pocket awl.
The No. 3 model underwent little change throughout history. For a very long time it was offered in all 4 available sizes and in all available variants. The small size model no. 4/3 was no longer listed in the 1964 catalogue, nor were the variants made of ordinary steel and horn scales, or only while stocks were still available.
Pocket knife No. 3 had a large cutting blade and a pocket awl. There was an optional hanger for this model.
Big cutting blade: 2.4 mm – 2.8 mm; Awl: 2.0mm - 2.4mm
In model no. 3, the head rivet held the large cutting blade in place, the foot rivet held the pocket awl, and a center rivet held the back spring in place. When closed, the pocket awl rested mostly on the upper scale/plate and the tip on the upper jaw.
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.
