So, most of you folks seem to be reasonably pleased about the coming of S45VN? I guess I just haven't caught the 45 fever yet. I wish someone would talk me into it. I'm sure it's good; maybe if it had been introduced a year ago I'd have gotten on board a little faster. Not sure what it offers above and beyond SPY27. A bit more corrosion resistance, maybe?
S45VN currently has a noticeable price advantage over SPY27.
“The main changes we expect from S45VN vs S35VN and S30V are an improvement in corrosion resistance due to the increase in Cr of about 1%. We expect a reduction in toughness when compared with S35VN because of the increase in total carbide content. The design including niobium and nitrogen additions should help maintain toughness similar to or better than S30V. Edge retention is covered later in this article. The increase in Cr in solution puts S45VN at a similar Cr-level to Elmax, but it is still somewhat below S110V and M390.”

As announced in the 2021 catalog, the standard-production Para Military 2 and G-10-handled Para 3 families are transitioning from CPM S30V to CPM S45VN. That's it. I'm not sure where "the word on the street" is coming from regarding a wholesale move away from S30V, but it's unfounded.

I know there has been a lot of talk about two other steels: SPY27 and MagnaCut. Let’s see what the next Reveal has in store.
Thanks RamZar, this pretty much answers all of the OP's questions in regards to S30V.
Now what about S35VN? Does it have any future in the Spydiverse at all, with S30V and S45VN, plus SPY27 and MagnaCut aka Larrinite?
Spyderco went back to S30V from S35VN on the Native5 a few years ago.
I know. I was lucky enough to grab a S35V N5 with full liners under G10 before those became unavailable.

I thought that SPY27 was supposed to be highly corrosion resistant? I would have thought better corrosion resistance than S45VN, though the latter’s corrosion resistance is supposedly improved over both S30V and S35VN.

I haven't heard that. SPY27 looks to be a functional duplicate of S35VN in most ways. The only testing I've seen suggests similar corrosion resistance to S30V or maybe a bit less.
S45VN seems to me to be basically be modern Elmax, or S30V with improved corrosion resistance and toughness. Not a radical leap, but more of an incremental improvement.
Edit: Whups, too slow on the draw, already addressed above.

Thanks!
Then it seems to me personally that S45VN is the better deal than SPY27, which will make a knife cost more. Not that SPY27 doesn’t also sound good, but…
