So if I understand it correctly. S90v would definitely be much more corrosion resistant which is a big concern of mine. However, I kind of want to live on the wild side and throw some carbon into my everyday carry. Is there an advantage for cruwear over s90v?

Some of my options I'm playing around with right now are on a para2, either going stock on the micarta cruwear or flytanium micarta on the s90v
 
Cruwear isn’t stainless but is hard to stain. They are quite a bit different and not two that I would normally “compare” when choosing between knife steel on the same knife.

Long story short. I’d take cruwear everyday over s90v. Twice on Wednesday. If stainless is your absolute deciding factor I wouldn’t use either.
 
Cruwear although not stainless is very stain resistant. Cruwear is much tougher than S90V. Although S90V will hold an edge longer Cruwear is no slouch in that area either. And a you can put a finer edge on Cruwear as it has much better edge stability. Cruwear also is a pleasure to sharpen.

Just my personal preference, As stated above, I also would take Cruwear anyday / everyday over S90V.

No one picks s90v for its corrosion resistance. It is fairly corrosion resistant, but the main reason to pick it is for the edge retention. Cruwear isn't really directly comparable; it usually gets compared to D2 because it's supposed to be like a more stainless D2.
 
S90V will be a true stainless steel with very high wear resistance. May be harder for you to sharpen depending on your skill level and what abrasives you're using (diamond or CBN will be the right thing to use for S90V). Not crazy high toughness but good for a stainless steel of such high wear resistance.

CPM CruWear has great toughness and will sharpen more easily due to its much lower wear resistance compared to S90V. It's not properly stainless steel, but does pretty well in my personal experience, though you can find reports of it corroding if you search around. For people who are not necessarily sharpening nerds, I think CruWear will be easier to live with in that respect.

The CruCarta PM2 is a great knife.

I liked the crucarta, but the smooth black G10 DLC cruwear is the pinnacle of PM2 for me! I think it was a KJ exclusive.1000009727.jpg1000009728.jpg
 
On a small knife like the Para2, I'd go with S90V because it has much better wear resistance and stain resistance, and Cruwear's superior toughness (resistance to chipping and breaking) is overkill on such a little blade.

On CATRA cutting tests, S90V will make 780 cuts and Cruwear will make 530 cuts to get to the same level of dullness. Diamond stones and a thin edge make sharpening a snap.

S90V's toughness is about 7 ft-lbs, well short of Cruwear's 23 ft-lbs. That's a big difference, but probably not needed on a small blade.

S90V's toughness is roughly in the range of 440C, S30V, D2 and 10V. But its wear resistance is much, much better than all of those steels but 10V.
 
I like the basic s45vn steel on the PM2 for it is a very balanced steel.

if you had to pick between Cruwear and s90v I guess you should consider the use you will have for your k’ife
If you will use for basic edc both will be fine and you can pick the cheapest or the one that looks better to you
If you plan to use it mainly to cut cardboard, s90v will be a more optimal choice
If you plan to beat on it (for exemple construction work), Cruwear will be more adequate
 
Like what others have said. I would pick the knife first and then decide on the steel. In the end you are buying a tool and it should be for the job you need it for but also should be comfortable too.
 
S90V will not be much different from S110V, just a bit tougher. If you find S110V chippy then get S90V. Otherwise, get the crucarta for something completely different from what you have that you can beat on.
 
Folders and smaller fixed blades, I prefer S90V.

I find that Cruwear doesn't offer any advantages over S90V for blades that are used for cutting and slicing other than being easier to sharpen. Recently, I've had the pleasure of using David Mary David Mary 62hrc AEB-L fixed blades that I'll somewhat abuse if I plan to touch up on the job, but I haven't had to yet.
 
I love both steels. They are both on Larrin's curve of perfect tradeoff between toughness and edge retention, where S90V has high edge retention, and CPM Cruwear less so, but more toughness (think "less chipping"). Also, CW is easier to sharpen.

Cruwear doesn't stain easily, but it does when you keep it wet overnight, for instance. I've never seen S90V rust myself.
 
Cruwear, All the way!!!

I've only got limited experience so far with it, but my knife has cut through more Onions than you can shake a stick at......and a couple elk, and a couple deer.

No Staining.

CATRA results are given in the total mm of depth that is cut into the 5% silica infused card stack over a fixed amount of cutting.

The results are not number of cuts.

However, the greater the number is the better the steel did in testing.

All the knives do the same amount of cuts; 120 slices or 60 cycles "back and forth" and the millimeters of cut depth into the card stack is logged with each slice and totaled at the end for the total cards cut (TCC) in mm.

So, the S90V did more work than Cruwear in millimeters of card cut with the same amount of cuts under a fixed 50N load thanks to the increased resistance to edge blunting and wearing allowing for more cut depth per slice.

No they are about the same. Take a look at Larrins website, knife steel nerds for more scientific data, but he rates
S90V and S30V @ 7.5/10

I can’t imagine either steel rusting easily unless the finish is very rough, like a bead blast. If they’re both satin they will be very good
 
As others have said, S90V is more stain resistant and holds a better edge in abrasive materials, which is what CATRA tests. Cruwear is tougher and less stain resistant and takes a very sharp edge easier. With the higher toughness it will tolerate thinner edges.
One thing to note with edge holding comparisons. Most folks here rely on CATRA, which is the industry standard. That measures edge holding in abrasive materials, but is not necessarily an indicator of edge stability in other materials. I have done a fair amount of testing to simulate my typical use, with a mix of cardboard, plastic jugs, and wood. S90V came out on top, but Cruwear and CTS-XHP weren’t far behind.
