Hummer, I have never had a rust problem with any knife. Keep it clean and wipe it always. I use high-stain carbon steel kitchen knives, they see a lot more moisture than any other knife except for diving.
That said, CRKT bead blast finish ***** (sucks). I won't get another CRKT knife until they drop the bead blast fetish. (Such as on the otherwise excellent Apache series.)
I would buy a small and a large S2 if they would only drop that crappy finish. :barf:
