CRK Magnacut vs S45 edge retention

For anyone that has used Chris Reeve Magnacut and S45vn which one has the best edge retention.
 
There may not be much difference in edge retention, although I haven't had their magnacut long enough yet to know for sure. I wonder if the increase in hardness boosts edge retention.

Having used both steels from CRK, the most impressive difference is not the toughness, per se, but the strength of the magnacut at 63-64. It resists deformation during hard cutting tasks. Things that would have rolled or chipped the s45.

That, along with superlative stainlessness, is what makes magnacut so good for cutlery.

By the way, I saw a recent video with Larrin. He said the sharpening angle makes the greatest difference in edge retention, even more so than chemistry or heat treatment. So, the short answer may be whichever one you sharpen more acutely.
 
I’m seeing a bit better retention and much better toughness. I’ve had now 3 instances that the magnacut was fine after something that I know would have chipped or rolled S45VN. I know because I’ve had to sharpen out the results on S45VN.
 
The hardness makers take Magnacut to makes a big difference, if they are going to 61-62c Magnacut is in the same group as 4-5 others and they are leaving a lot of performance on the table. Why use it if they aren't going to 63-64? Larrin is probably the only one who has run good tests of one alloy VS another. CR Magnacut VS CR 45VN? Chris is probably the only one that could answer that.

Which is exactly where CRK runs it.

Stop, you’re making me think that my 21 with S35VN is outdated.

"Come over here and say that..."
 
I’m exhausted by this on-going debate of what HRC MagnaCut should have. I own a 63/64HRC MC CRK but have not used it yet. I do own a 62HRC MC Roosevelt and it is really great. For a blade that’s very TBE it has no edge rolls or chips that some of my other steels have after using them for the same tasks.

I saw a post on IG today about one of the Hinderer guys, Sam, who said they run their MagnaCut at 60-61 HRC “which focuses on toughness” and he also said according to Niagara anything above “63 HRC is “not good” and you’d be better off running it at lower HRC.

If it’s “not good” why would CRK run it that high? I don’t believe the “not good” claims.

I don’t have enough experience but I’d assume it would be really hard to notice the difference in edge retention between CRK’s MagnaCut and S45VN.

In with popcorn for the reaction to this.
 
I like buttery popcorn. The same answer I always say over and over what do you intend to use the knife for. i understand one of the best properties of CPM Magnacut is rust resistance. It's also expensive but a very good steel for a wide range of cutting tasks. Can you get everything you would ever need or want for your cutting tasks with a less expensive steel that may or may not perform better for what you want than Magnacut.

I do like everything I hear about Magnacut but in all honesty the above question still is valid.

Smart. This is one of those "ain't necessarily so" situations. There are several factors in the mix...and that's all I've got to say about that.

(But I am admittedly a fan of MagnaCut.)

I have been using my Spyderco Native Salt in Magnacut for a bit now and I am sort of smitten with the steel. Just received a small Inkosi in Magnacut and I can’t wait to put it through the paces.
 
Per Larrin (I can't seem to post the charts) S45vn should be ~61.5 rc with ~6 ft/lbs of toughness, whereas magnacut goes from almost 18 ft/lbs at 60.5 rc to 10 ft/lbs at 65rc (16 at 63, 12 at 64). So I guess over 63 is "not good" bc that's when you leave prybar territory?
