Sorry , guys - guess my reply did sound a bit opinionated. I sailed actual rigged boats on SF Bay for a few years. I haven't looked at Spyderco's literature for quite a while so I made a mistake between H1 and H3 - won't try to be so specific next time. I said the people on this forum take care of their knives, so why are you sending me nasty grams telling me how you take care of your knives? I made 2 knives for sailors out of 440C a few years ago. The knives were passivated to remove any carbon particles and buffed to a mirror finish (both of which should be done for a knife for salt water use). I told the buyers not to store them on the boat in a leather sheath and to wipe them down with BoeShield periodically. Six months later the first buyer brought his knife back because it was rusty. Nine months later the second buyer brought his back because it was rusty. Turned out both buyers stored their knife in a leather sheath and never wiped them down with anything. I gave them their money back and have, ever since, included a short paper on "the care and feeding of your knife" with every knife that goes out the door. So yes, Corrosion and care of a knife is a hot button for me, as a knife maker.
