The model no. 134 k was a model no. 234 k, which had a Phillips screwdriver instead of the corkscrew.
According to Victorinox, this Phillips screwdriver was developed in 1952. The model no. 134 k thus has a relatively short hihistory. This screwdriver may have been around a little longer, say since 1950. Rare examples of model no. 134k appear, with the old can opener that was superseded by a new model in 1951. It can be assumed that after the introduction of this new can opener with an improved function, the old version was no longer used. Therefore, a model no. 134 k with an old can opener should not even exist.
Throughout hihistory, the No. 134 k model has evolved steadily. The Phillips screwdriver in particular constantly changed its form and function.
The model no. 134 k has six functional parts. In addition to a large and a small cutting blade, there is a bottle and a can opener and on the back an awl and a Phillips screwdriver.
There was the model no. 134 k with or without a toothpick/tweezers and with or without a hanger.
Large cutting blade: 2.4 mm (later 2.5 mm); small cutting blade: 1.8 mm (later 1.6 mm); Screwdriver: 2.2 mm (later 2.0 mm); Can opener: 2.2 mm (later 2.0 mm); Phillips screwdriver: 2.8 mm (later 2.6 mm); Awl: 2.2 mm (later 2.0 mm)
The No.134k model requires four rivets for assembly and has two layers. The upper layer consists of the screwdriver and can opener as well as the awl on the back. The lower layer consists of a large and small cutting blade and the Phillips screwdriver on the back, also fixed with the same rivets. The fourth rivet holds the two back springs in place.
Cellidor red was used as the scale material, later also other color variants.
At the beginning of production, the intermediate layers and sinkers were made of German silver. Later, only the intermediate layers were made of nickel silver and the liners were made of aluminum. In the end, both the circuit boards and the intermediate layers were made of aluminum.
