Model No.247 has a special history. In addition to model no. 248, it was the only official 1-ply model from Victorinox in size 91 mm. It first appears in a handwritten note in the 1932 catalogue, which is why it can be assumed that the beginnings were probably in the late 1930s. The can opener changed in 1946. This then remained in place until the end of production around 1970, each time with the note Büxsenöffner 1946. This is astonishing, since a new, improved can opener was already being produced and used from 1951. This was the only model that still used the old can opener for a long time. Why is unclear. Apparently there was a demand for this particular model.
From about 1952 the position of the can opener changed. From then on it could be opened from the back and was in the position behind the large cutting blade. For this, both the can opener and the large cutting blade had to be made new and different. In early 1970, Victorinox ceased production of the No.247 model. Instead, model no. 247k appeared once in the catalogue, from which it then disappeared again.
Model No. 247 had a large cutting blade, a can opener and a corkscrew on the back. The model was available with or without underwire, never with tweezers/toothpicks.
Big cutting blade: 2.7 - 2.8 mm; Corkscrew: 2.8mm - 3.0mm; Can opener: 2.3 mm (later 2.0 mm)
Model no. 247 is a 1-layer pocket knife. The large cutting blade moves around the head rivet, the can opener around the base rivet, and the corkscrew on the back around the middle rivet. The optional bracket was attached to the foot rivet.
For model no. 247, according to the 1932 catalogue, Victorinox used Elsenid ( Cellidor ) and horn in the carbon steel variant as scale material, as well as mother-of-pearl and tortoisescale in the variant with tools made of rust-resistant steel. From the mid-1940s, only variants with Cellidor bowls are listed.
Victorinox always used nickel silver rivets for model no. 247. The liners and intermediate layers were originally also made of nickel silver, later made of aluminum.
