Little is known about the No. 145 k model. It does not appear in any trusted official Victorinox catalogue. This model is a model no. 245 k, which has a Phillips screwdriver on the back instead of the corkscrew. These 3 layers, which were installed for this model, are known from other models. The combination of scissors and long nail file on the back was used in some models, as was the combination of small and large cutting blade and Phillips screwdriver on the back. The 1st layer with the screwdriver, can opener and awl on the back was a standard layer at Victorinox, which was installed in many models. Therefore, it is basically not surprising that a model no. 145 k existed and was produced by Victorinox, since all the necessary components were available.
Either the model no. 145 k was only produced in very small numbers and was therefore not noted in the catalogs at all, or it was made to customer specifications. A model no. 145 k with horn scales, which was produced for General Motors GM, is known. But there were also models No. 145 k with scales made of mother-of-pearl or Cellidor. This model was manufactured from the 1950's to the 1970's and is highly sought after by collectors due to its rarity.
In addition to the tools of model no. 134k (large cutting blade, small cutting blade, screwdriver, can opener, awl and Phillips screwdriver), model no. 145 k also had scissors and a long nail file. The model was available with or without a toothpick/tweezers and also with or without a bracket.
Large cutting blade: 2.5 mm; small cutting blade: 1.6 mm; Can opener: 2.2 mm (later 2.0 mm); Bottle opener: 2.2 mm (later 2.0 mm); Scissors: 2.5mm; long nail file: 2.5 mm; Phillips screwdriver: 2.5mm; Awl: 2.2 mm (later 2.0 mm)
The model no. 145 k was a 3-layer pocket knife. The bottom layer consisted of small cutting blade, screwdriver and Phillips screwdriver on the back; the upper layer of large cutting blade, can opener and awl on the back. Between these layers, in a separate layer, were the scissors with a long nail file on the back. Compared to the similar model no. 235 k, the scissors do not move around the foot but around the head rivet.
Cellidor red and rarely horn or mother-of-pearl were used as the scale material.
In the beginning, liners, spacers and rivets were made of nickel silver. Later, aluminum liners were used, as were the intermediate layers, but nickel silver was still used.
