Victorinox had the designation "officer's and sports knife" protected by law. At the same time as the 91 mm variant (No. 205), Victorinox produced the same model in 84 mm, model No. 206, later 234 k (k stands for "small" and means the size 84 mm ).
The first series still had four visible rivets. After that, the screwdriver changed to a combination screwdriver/bottle opener. Later the shape of the can opener changed, even later the rivets disappeared under the scale, then the external awl was integrated, etc.
Like all army knives, the model no. 234 k has undergone major developments and changes over the course of history. It is still in production to this day.
The model no. 234 k has six functional parts. In addition to a large and a small cutting blade, a bottle and a can opener, and on the back an awl and a corkscrew.
There was the model no. 234 k with or without a toothpick/tweezers and with or without a bail (later the ring).
Large cutting blade: 2.4 mm (later 2.5 mm); small cutting blade: 1.6 mm; Screwdriver: 2.2mm; Can Opener: 2.2mm; Corkscrew: 3.0 mm (later 2.5 mm); Awl: 2.0 mm
The No. 234k model requires four rivets for assembly and has two layers. The upper layer consists of the screwdriver and can opener as well as the awl on the back. The lower layer consists of a large and small cutting blade and the corkscrew on the back, also fixed with the same three rivets. The 4th rivet holds the two back springs in place.
Fiber was originally used as the scale material, later also horn, staghorn, tortoiseshell and mother-of-pearl. Celluloid/ Cellidor later replaced fiber as the scale material.
Nickel silver, aluminum and brass were used for the liner material and for the spacers, and nickel silver, brass and steel for the rivets.
