Maybe I'm looking in the wrong places, but I'm not seeing that. Take Victorinox Climber for example.

History they tell you that
Under
Variations they tell you that the 1891–1991 Centennial Climber was released in 1991, the Damascus Climber was released in 2011, the Beijing Opera Climber was released "in the late 2000s??" But they do not give the year of first production for Climber, Traveller, or earlier Swiss Army Knives with this tool configuration.
Some knives with shorter production histories do have first production dates: Champion (1952), SwissChamp (1985), Cybertool (2000), etc. But the most popular knives — Classic, Spartan, Tinker, Super Tinker, Climber — mostly draw a blank.
