Victorinox in the early 1950s together with the other models in 74 mm format and was completely withdrawn from production in the 1980s.
The model no. 650 has a large blade and a nail file. Toothpicks and tweezers never existed. Model no. 650 with a key ring was very rare. In the Celluloid/ Cellidor and Alox red with cross versions, the pocket knife was sometimes available with a hanger.
Big blade: 2.3 mm; Nail file: 2.3 mm
The knife consisted of two scale parts, two spacers, two springs and the functional parts of a large blade and a nail file. As with the smaller relative no. 620, four rivets were used, each of which fixed a spring or a functional part. You can see a notch in the upper spring on the right in the picture. This notch has no function with this type of knife, but was used to “float” the opposite spring on models with three or more functional parts.
Up until the 1970s, the scale material was aluminum in red with a cross, gold and blue-green, or cellidor /celluloid in tortoiseshell, mother-of-pearl or red with a cross, horn 2nd class and engine-turned steel. Other colors were added later, notably silver and blue for Aluminum and black for Cellidor.
It seems that this model never came with real mother-of-pearl, tortoiseshell or gold scales and never with tweezers and toothpicks.
the scale material celluloid/ cellidor, horn and steel. At the beginning the liners were made of brass, later made of nickel silver. In the case of aluminum scales, the circuit liners were completely dispensed with. This was possible because aluminum is relatively rigid and hardly warps. From around 1960, Cellidor was no longer riveted but glued, which is why the circuit liners were used as the carrier material for the glue.
