H1 steel is
Id go with the H1... I have an H1 steel spyderco knife and it has performed great. I cant speak to its ability to take saltwater(numerous youtube vids and forums can do that for you) but the build quality on my NE H1 Salt is great!
H1 steel is
Salt is a series of knives by spyderco. there are many options to choose from. The one thing that they all have in common is that they all use spyderco's H1 steel which is supposedly rustproof. I am picking one up friday for a friend from knifeworks.

It has carbon, just less, and its the iron in the steel that forms rust not the carbon. This is why talonite (cobalt + chromium) and titanium dont rust because thay do not contain iron (non-ferrous alloys). Tho with that makeup Id honestly would like to see what it would take to make it rust! It would take some serious chemical oxidizers id imagine to get it to even discolor some.
Not really. For all practical purposes it seems like it would pretty much be what you said. You would have to try super hard and probably use some chemical means to get it to do anything even visible. I just hate for people to think all stainless steels are 100% rust prrof. They are more like very corrosion resitant for the most part.My Bad
