From the 1940s, Victorinox produced two special pocket knives that were used for processing linoleum floor coverings. The model number is unknown. They were marketed as "Linoleum Hooked Knives" and "Model Giubiasco". The special thing about these pocket knives was that the blades were interchangeable. The "linoleum hook knife" had a hooked blade. The "Giubiasco model" had two blades, a hook blade and a special blade that had a cutting edge on both sides. If you opened the blade, it locked. The lock could be released with a push button in the scale. The name "Model Giubiasco" was derived from the town of Giubiasco in Ticino, where a large linoleum factory was located. It is unclear whether Victorinox developed and produced these special pocket knives specifically and exclusively for the company "Linoleum Giubiasco AG". The advantage of the interchangeable blades was that the entire pocket knife did not become unusable with constant use, but only the blade could be replaced.
The Giubiasco model was certainly made until the 1970s. The handle was later made of nylon and the rivets disappeared under the scale.
The "Linoleum Hooked Knife" and "Model Giubiasco" models had interchangeable blades, a hooked blade and/or a special double-edged blade.
Hook Blade: 1. 8mm or 3.0mm; Special blade: 1.8 mm
These models were 1-layer pocket knives. The interchangeable blades were not firmly fixed. Opening the blade put tension on the back spring, which released when it was fully open, preventing the blade from closing again. With the Giubiasco model, the blade snapped into place completely.
Victorinox used beech or rosewood as the scale material for both models, and later nylon for the Giubiasco model.
The rivets and spacers were made of brass.
