I just got a CN-121, and it triggered some interesting observations. I am also starting to wonder if the Swiss companies were somehow involved.
The CN-121 is *identical* to a Wenger Diplomat and a Victorinox Buddy (or Secretary); so much so, that they had to be made from the same plans. (Although maybe the plans are widely available, like certain other Army types.) Other than tang stamps and markings on the handle, the only noticeable difference is the way the little ring is connected.
A couple of the other Century models look very very similar to Victorinox. Handle and blade (including can and bottle openers) size & shape look too close for coincidence. I wonder if Victorinox had some experiment running or collaborating with a German plant?
Now it would be very interesting to get the low-down from an insider.
