Outside of the US or at least outside of English, a Swiss Army Knife is known as a pocket knife, and they’re not always Swiss-made either. As you can see from Victorinox’s own website (and they are the official manufacturer of what Americans call the Swiss Army Knife - which, indeed, got famous because it was used by the Swiss army), they call it a Taschenmesser, where Tasche translates to pocket and… I think you can guess what Messer translates to.
