Model No. 314 first appears in the 1922 Victorinox catalogue. At that time it was a basic model no. 308 with an additional saw. A short time later, production of this model was discontinued, and from 1932 a model no. 314 appeared again, but with a completely different tool configuration. It had a characteristic very long edged awl and a corkscrew on the back. The model was available with the version "carbon steel" or "rust-resistant steel".
The models no. 315 and no. 318 appear for the first time in the 1932 Victorinox catalogue. These 3 models were produced until around the mid-1960s and then discontinued by Victorinox - like the other models in this pocket knife series.
The original model No.314 had an additional saw in addition to a large and small cutting blade, a screwdriver and an awl. The later, new model No. 314 still had the large cutting blade and the screwdriver (this time with a stripping function ), but also an additional angular long awl, a can opener and a corkscrew on the back, but the saw, short round awl and the narrow one were missing cutting blade. The No.315 model had a slim screwdriver in place of the can opener compared to the new No.314 model, and the No.318 model had an additional saw compared to the No.315 model.

Big cutting blade: 2.4 – 2.6 mm; Corkscrew: 1.8 - 2.0 mm; Screwdriver: 2.0 – 2.2mm; Can opener (or narrow screwdriver): 2.0 – 2.2 mm; long awl: 2.0 – 2.2 mm; Saw: 2.0mm
Structure (new version)
The models no. 314 and no. 315 are 3-layer pocket knives. The top layer contains the screwdriver and the can opener (respectively narrow screwdriver), the bottom layer the long awl and the corkscrew on the back. The middle layer consists of the large cutting blade. The head rivet made of nickel silver, together with the 2 jaws, fixes the wide screwdriver as well as the large cutting blade and the long awl, the foot rivet the can opener (or narrow screwdriver), an intermediate layer and the back spring of the lower layer. The middle rivet is used to fix the two scale parts, the two upper back springs and the corkscrew on the back. Model No.318 is a 4 layer pocket knife with the additional layer of the saw making up the 3rd layer from the top.
Only red fiber was used as the scale material, with the exception of the original model no. 314, which also included horn and staghorn.
When carbon steel was used, the sinkers and rivets were steel; in the case of tools made of stainless steel, the liners and rivets are made of brass, with the head rivet and the jaws always being made of nickel silver and the intermediate layer made of brass.
