The model no. 137 k is a rare pocket knife, which was only produced in very limited numbers and only for a short period of time by Victorinox. The difference to model no. 237 k is the Phillips screwdriver on the back, which replaced the corkscrew from model no. 237 k. This was developed around 1950.
Model No. 137 k was produced by Victorinox until the 1970s, after which - as with model No. 237 k - production was discontinued.
Compared to model no. 235 k, where a variant with a long nail file on the back was produced (model no. 245 k), this seems never to have been the case with model no. 237 k. As a result, there is no model no. 247 k. Apparently it was not technically possible to use the long nail file in the same position as the saw. As a result, there is only the combination with a long nail file and scissors.
In addition to the tools of model No. 237k (large cutting blade, small cutting blade, screwdriver, saw, can opener and awl), the model no. 137k had a Phillips screwdriver instead of the corkscrew. The model was available with or without a toothpick/tweezers and also with or without a bracket/key ring.
Large cutting blade: 2.5 mm; small cutting blade: 1.5 mm; Can opener: 2.0 mm; Bottle Opener: 2.0mm; Saw: 1.75mm; Awl: 2.0 mm; Phillips screwdriver: 2.5 mm
The model no. 137 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, was the saw.
Celluloid/ Cellidor red was mainly used as the scale material.
The boards were made of aluminum, the intermediate layer of nickel silver. Other variants were also possible.
