Both carbon and CRES (‘stainless’) steels can rust. The propensity to rust depends upon the amount of alloying elements, but ‘plain carbon’ is generally the worst and the 400-series stainless and similar compositions (like AUS-6 and AUS-8) are generally pretty resilient to corrosion; outside of a salt spray environment they’re generally limited to some spotting and staining, although I had the blade on a Leatherman that was kept in a PFD that I used for kayaking break due to corrosion-induced fracture.r
The special alloy used in the old Puma knives was both hard and extremely rust resistant. Then again, they aren’t cheap.
There are many wonderful sites dedicated to knives and knife - related questions. There is much knowledge to be acquired (and friends to be made) on Blade Forums, Knife Forums, Jerzee Devil (my fave) and others.
Go check 'em out!
