It's hard to keep everyone happy that's for sure, but I get a lot more requests for stainless due to the nature of who will be using them. yes... IF you take care of them carbon steel knives will be relatively rust free, as TLR said, salt water can be brutal. I even had one knife made of 440c that went to the jungle for 3 months that came back spotted in orange, so I can't imagine one of my carbon one's condition after that, and I have been offering coatings on the carbon to help with this. it's a hard nut to crack keeping everyone happy but if anyone had "the answer" I guess we'd all be using whatever the answer is ...besides INFI of course. can't wait for stainless INFI, it's gonna be awesome!
