> are English as a second language writers who perhaps came across it somewhere
Your prejudice is showing. Where would you even get an idea like that?
I hope you understand that people whose first language isn't English also use SAKs. It's not just an English thing. They're not trying to repeat some unknown object they've only encountered in metaphor. The tools are literally Swiss. And popular around the entire world.
You’re absolutely right. I was just in Switzerland and I’ll tell you the Victorinox shops have endless visitors from all kinds of tourists. Swiss Army knife metaphor is timeless, at least for those who go out. Maybe there’s a generation where outdoor activities is an unknown because computers. At this point the other person is just being argumentative.
I'm being argumentative? Uproarious.
Arguing that my observations are invalid because you were in a Victorinox shop in Switzerland is the chef's kiss on this ridiculous discussion.
In the future, just move along. The other argumentative guy had no reason to get defensive about SAK, and this whole worthless discussion, from a basic observation about idioms and ill-suited tools, is a waste of bits.
