swiss pocket knives

No. 72

history

The No. 72 model was developed by Victorinox in the 1920s. It is identical in design and construction to the smaller model No. 52.

This model was produced until the mid-1970s and was relatively popular.

On the picture on the right you can see the different coloring of the circuit liners. This was a consequence of the celluloid used as the scale material. The side of the liner that came into contact with the scale shows strong signs of oxidation, while the other side, which was inside the pocket knife, is completely shiny. The celluloid also led to severe oxidation of the rivets or the metal inserts (e.g. company name). There were often cracks and tensions within the scale or the material contracted. Later, celluloid was completely abandoned and only Cellidor was used to imitate expensive materials.

functional parts

In addition to a large and a small cutting blade, model no. 72 had a long nail file on the back.

The variants with a red Cellidor bowl with a cross, mother-of-pearl and horn were also available with tweezers and toothpicks, the Cellidor red variant with a cross also had a bail/ring.

material thickness

Big blade: 2.4 mm; small blade: 1.2 mm; Nail file: 2.4 mm

construction

This model has a spring on which all three functional parts move. To make this possible, the spring is branched on one side. This makes it possible for the small blade, like the nail file opposite, to rotate at this point and always be under tension. A center rivet holds the spring in place, while the other three rivets hold the three functional parts in place.

scale material

Black oxidized steel was used as the scale material, cellidor in imitation mother-of-pearl and tortoiseshell imitation and red with cross, horn, tortoiseshell, mother-of-pearl and engine-turned steel.

Liners, interlayer, rivets

The liners, intermediate layers and rivets were made of German silver.
