You know, it's funny. My Grandfather was from Switzerland. He came to the US shortly after WWI. Actually there was a small migration of Swiss to the Oregon coast at that time. Growing up, we talked about Swiss Army knives and what not.
We knew Wengers were the real deal because the name was close to the names of various families in the Swiss Society.
We had our suspicions about Victorinox, because the name looked French to us (why I don't know
) but one of our lines of "reasoning" is that no one we knew had a name that ended with an X.
