Indeed there is a sweet spot. I would rather trade sharpness and more careful maintenance for corrosion resistance. Others would not. I had a housemate that tossed knives in the sink and left them there for days, their Victorinox only showed light rust. You couldn’t really cut anything with them but that didn’t seem to be the point.
I also had a partner who loved Victorinox parers and serrated parers, they could do anything with them and rarely used anything else. Your mileage may vary of course, and I bitched everytime I sharpened them, which was weekly.
