Haha it's not in any way scientific, but here's a snippet from my post in another Spy27 thread..

Also, a note on corrosion resistance.. I carried my SPY27 P3LW most of the last week. It's been hot and very humid in the northeast lately. Between Saturday and Sunday, I hiked a little over 13 miles in ~95 degree weather with the knife in my right front pocket. I don't sweat like some people do, but that's about as sweaty as I get. I hadn't treated my blade with anything, and honestly, didn't even remember to wipe it down or anything post-hike Sat or Sun.. When I thought to check on it though, there was absolutely no sign of any corrosion.. no spotting, staining, or signs of rust at all. YMMV, but as far as I'm concerned, SPY27 is absolutely good to go for my needs when it comes to the corrosion resistance department..
Not that I generally have issues with rusting S30V.. but given a choice between the two, I'd be more comfortable with Spy27 in my pocket in a corrosive environment. I'm not sure how it will perform for you out on the kayak, Lance, but for me and my uses, Spy27 has exhibited a reassuring level of corrosion resistance..
..well, that escalated quickly..
