Victorinox produced model no. 202 ½ between around 1940 and 1970. In principle, it was the basic model no. 200, except that a narrow screwdriver was fitted instead of the can opener. Victorinox manufactured the No. 202 ½ model using carbon steel or stainless steel tooling.
Why this special designation "1/2" was chosen is unclear. Possibly there were simlayer too few numbers between No. 200 (soldier's knife) and No. 205 (officer's knife).
The pocket knife No. 202 ½ had a large cutting blade, a screwdriver, a narrow screwdriver and an awl.
Large cutting blade: 3.4 - 3.7 mm; Awl: 2.1 mm; narrow screwdriver: 3.0 mm; Screwdriver: 3.0mm
The pocket knife No. 202 1/2 was a 2-layer model. The upper layer consisted of a screwdriver and a small screwdriver, the lower layer of a large cutting blade and an awl. The screwdriver and the large cutting blade turned around the head rivets, the other 2 tools around the foot rivets.
Victorinox used red fiber as the scale material for this model.
The liners and the rivets were made of steel or German silver, the intermediate layer of brass or German silver.
