My most corrosion resistant PM2 are the M390 copies: beats S30V and S35VN, check out the literature, for example:
All in all, if you can find one and want wear resistant and hard, I recommend M390, such a cool material.
That chart is incorrect regarding S110V. S110V is about as stainless as you can get without going to a fully rustproof alloy. It's much more corrosion resistant than S30V, S35VN or M390. S110V is also superior in wear resistance and hardenability.
S30V is an old standby for a reason, a much better steel than you might think. Many folks, especially around here are chasing after new
and exotic things, but you really can't go wrong.
S35VN - nobody can tell the difference between this and S30V, but if you like brown scales, go for it. Definitely don't pay extra for it.
S110V - great stuff, fantastic even. Some people fuss about sharpening it, others say it is not a problem. But you will hardly need to sharpen it.
M390 - this and Cruwear have an enthusiastic cult following. Good stuff, but the main drawback here is that you are going to either have to pay big money and buy from a scalper on the "secondary market" or wait for a new run (which is overdue). If you decide to wait, realize that 20CV and 204P are essentially the same thing. One of them may pop up before another PM2 in M390 (I am hoping for one of the alternatives).
All of these are plenty stainless, so unless you live near the ocean or know you have corrosive sweat, there is no reason to chase after a DLC coated blade. But if you think a black blade is your thing, DLC is amazing stuff.

S110V is also a b*tch to sharpen, at least for me. That's why I didn't recommend it. The S110V PM2 is certainly cheaper than the M390, so that speaks for it.

It's pretty strange to me that OP asks for a very corrosion resistant steel, and without asking for details half the responses assume he doesn't need any more corrosion resistance than the person replying.
If M390 tickles your fancy you might want to pick up the bento box shop m390 Para 3 before they are gone. The price is very nice and you get it straight from them.
Most recently acquired: Military 2, Paramilitary 2 Tanto x2, YoJUMBO, Swayback, Siren, DLC Yojimbo 2, Native Chief, Shaman S90V, Para 3 LW, Ikuchi, UKPK, Smock, SUBVERT, Amalgam, Para 3 CTS-XHP, Kapara, Paramilitary 2 M390 Grail Paramilitary 2 M390 X 2! ACHIEVED!!

But he didn't really say that -- he asked for a steel with "the best combination of corrosion resistance and ease of sharpening" and now that I reread his original question he seems a lot more concerned about sharpening, and has experience with Cruwear. We have to read between the lines a bit, but we all know Cruwear sharpens like a dream, so he must be unhappy about Cruwear and corrosion. Not a problem for me, but his mileage must differ.
Given that, it seems like one of the M390 family would be a good choice, but S30V is still a candidate. Ease of sharpening would rule out S110V.
In which ways do you find M390 easier to sharpen than S30V, and more corrosion resistant than DLC'd S30V? I've had the opposite experience, though I do think M390 is a very fine steel.

Who me? I have never had the least bit of corrosion with either steel. So I cannot offer any experience of my own other than to say just that.
The forum gossip I have heard leads me to believe that most people find M390 more corrosion resistant that S30V, but I am surprised to hear
that it is an issue with either steel. And I file away your comments as valuable and entirely valid, but I would be pleased to hear more details.
I was very happy to get DLC on an M4 blade, but then read a bunch of people saying that steel can rust just fine under a DLC coating,
which was a big surprise to me and kind of let the air out of my balloon. Not sure what to say about all that.
I've got a PM 2 in S110V and I can't say enough good things about it. Now my current favorite EDC is my hallowed C-36 Spyderco MILITARY model with M390 blade steel. That's been my "GO-TO", all purpose EDC PE Blade for about two years now and I just can't say enough good about it. But both steels are great and I guess I like the M390 better is because it just seems to take punishing jobs really well. If you can find one of those PM 2 models in Cruwear or XHP those would be my next choice.

Do you have the background data for this chart because it doesn't match up with my database? I would love the opportunity to update my info if my data is incorrect.

It's just a quote from Matt Davidson, http://knifeinformer.com/discovering-th ... nife-steel, his personal opinion. Being roughly one year into this new hobby, I find it next to impossible to find scientific data of more than just a few steels from the same manufacturer.
I have 2 PM 2’s in S35 VN and S110 V. My comments reflect my experience. Unless you’re in a very humid environment. Like in or around salt water I’m pretty sure the difference in corrosion difference is insignificant among the stainless options here. S35 VN and S110V are not hugely different in terms of sharpening though the S110 will take longer but will hold an edge better. The longer time between a full session of sharpening makes the 2 pretty even in maintenance terms. I don’t own a DLC coated blade so I can’t speak to that but a coated stainless blade is as rust resistant as anything short of H1 or LC 200N.
