Could somebody please tell me about Cruwear and how it compares to other steels? I’m all about a PM 2 in Micarta.

Michael Christy gives a great overview of CruWear and K390.

Cruwear and K390 are both carbon steels that will patina, maybe rust, under certain conditions. They are pretty far off in terms of performance- Cruwear is prioritized for toughness but is not the best for edgeholding, K390 is prioritized for edge holding but isn't very tough. I think the properties of Cruwear are good for the PM2. I've read of several people who have broken blades in S110V and Maxamet- they would be better off with Cruwear.
What does Michael Christy know about steel?? Kidding...Michael Christy gives a great overview of CruWear and K390.
Is that lagunitas??? Great drink !Both. May be a while before the Micarta comes out. I have mine on preorder.
When people say "give it a patina to protect against corrosion", that's a really vague statement. You can use a chemical agent or vinegar to promote the formation of black oxide on the blade surface, which is a stable oxide that gives a little bit of protection from rust (red oxide) to the steel underneath. Some "patinas" are not black oxide but just mild forms of oxidation that are not really protective.
K390's toughness is fine.
Yeah, or you can just paste wax it before it patinas or rusts. I keep all mine looking just the same as my stainless knives. It takes about 3 or 4 minutes to coat the knife and another minute to wipe it off. It looks better than when it was new because the wax micropolishes stuff off you couldn't see and it gets shiny and pretty. It looks better to me than any rust/patina.
Paste wax? How do I do that or is there a brand?
I tried Ren wax on my M4 blades and it didn't seem to help much. I experimented with some carbon steel nails and found that something like Birchwood Casey Sheath worked much better. I know that lots of people do these tests have their favorite protectant so use what you like best.I use Rennisance wax.
Huh, so REX 45 is reasonably tough? I was under the impression it was a tad brittler for some reason.I'm not an expert.
Cruwear is a favorite of mine.
It's Tool steel comparable to rex 45.
A little less edge retention than rex.
Rex is supposedly more brittle than cruwear and hap 40.Huh, so REX 45 is reasonably tough? I was under the impression it was a tad brittler for some reason.
