If you go to most jungle areas of the world, the indigenous people almost always use carbon steel knives (and machete/variants)
Rust isn't a real problem for them because they use the blades all the time.
The only carbon blade I ever had pitting from rust is my Bark River Bravo 1 and that was only because my daughter let it soak in the sink for a couple of hours before washing it.
This knife was made sometime between 1936 and 1938, I have owned it for 30 years.
It is my favorite hunting/camping knife.
