To M4 or not to M4...
To M4 or not to M4...
All you M4 lovers out there, I'm curious; would you take Rex 45 over M4 in dealer exclusives/standard production models, given how similar the steels are? Since Rex 45 is a slight improvement over M4 in edge retention, stain resistance, and ease of sharpening, it seems like a given, but that's just my take.
Re: To M4 or not to M4...
Tough call. I agree that it might be a slight improvement, but man I love M4. I think just for name recognition's sake, this wouldn't happen anytime soon. Maybe not the perfect example, but M390 still seems to still have a bigger following and a more perceived value than 20cv.
Hopefully we'll see some Pakkawood REX45 Knifecenter exclusives out of Golden :)

Re: To M4 or not to M4...
I answered yes only because I've liked hap40 in my seki models and I'd like the chance to try more rex45 in other golden models (manix!). I have no issues with m4, though.

No. While I don't have anything in Rex45, I really love the way m4 sharpens and performs. One of my favorites.
Re: To M4 or not to M4...
No. A new steel doesn’t lessen the proven goodness of an old one. But, I am game for more Rex45.

I disagree that REX45 has more corrosion resistance than M4.
My REX45 PM2s blade was the same color as the handle within 2 hours at work. M4 on the otherhand, has only the slightest patina after a year of use.

Re: To M4 or not to M4...
My 4V Manix behaves kind of similar to my Rex 45 knives (hardness and wear resistance). Obviously geometries are dramatically different, just saying.
Re: To M4 or not to M4...
All of my m4 knives are excellent performers, not a questionable one in the bunch, so maybe.
But if I get several more rex45 knives that perform as well as the only one I presently have, then yes.

Re: To M4 or not to M4...
I want some REX 45 knives or just one.
But, I'd rather have M4. Old tried and true.

Re: To M4 or not to M4...
I'd also be interested in another run of the 4v Manix (or a st. Nick's version). I love my cruwear Manix and I've read that 4v and cruwear have similar properties, but with 4v being slightly less rust-resistant. I'm just now trying out 4v.

Re: To M4 or not to M4...
M4 is my favorite Spyderco steel, I have 5 of them for various uses. IMO a replacement for M4 should have similar edge-holding but better toughness. Otherwise why bother.
Re: To M4 or not to M4...
M4 is by far my favorite steel, but I haven’t had the chance to test Rex45 yet. Really looking forward to the rumored shaman sprint.

Re: To M4 or not to M4...
Where is the option to replace M4 with Cruwear?? :D Jade plus DLC Cruwear would be been a dream combo for me.

Re: To M4 or not to M4...
I think the OP is looking at a possible upgrade to m4, not downgrade. :D
Re: To M4 or not to M4...
Rex 45 has less carbon and the roughly the same chromium, you shouldn't see more rust, you should see less. The general consensus is that Rex 45 is less prone to rust than M4. My own experience, as well as others from this forum, have shown this to be true.
My own testing, as well as 4 others that I'm aware of, show Rex 45 with slightly better edge retention. Maybe it's possible you got one of the "softer" ones? Maybe it's not at 66-67 hrc, but 64-65. There were a few that were found to be in the 64-65 range, it's bound to happen from time to time. If you have multiple Rex 45 knives and and find M4 stays sharp longer, then I would assume you have a stellar example of M4.
