Yeah the resistance to deformation from the increased strength came in handy here I feel.

Re: CPM REX 45 | Edge Performance
I have no idea I could only speculate, send one over and wait 2 years later and we'll see.

Higher edge retention than REX45 but maybe it would be brought undone by lower edge stability due to larger carbides?Deadboxhero wrote: ↑Thu Dec 01, 2022 2:53 amIt is pretty cool, the problem is it's difficult to compare apples to apples without more control seems there could be kind of a paradox in the knife community where controlled testing is not good enough and real world testing is not usable. Yikes.
Of Course realistically they're supposed to go hand in hand.
The problem is it took two years to get this anecdotal real world account.
Given how many steels there are in existence, none of us would live long enough to see testing like this on every steel.

Re: CPM REX 45 | Edge Performance
Do you know what he normally cuts on a regular basis? Curious if he'd enjoy Maxamet, he doesn't seem to be abusive to the edge. (No giant chips or big piece of missing tip)
Got a Maxamet Para 3 second to test out for myself for regular "heavy" use (cutting dirty rope, cardboard, etc)

Re: CPM REX 45 | Edge Performance
I did cut dirty rope, cardboard and even thin plastic buckets with my Maxamet 5 with no problem. But the pressure on the edge must be vertical, if there is any torsion that can lead very fast to chipping. I've had only minor chipping on the Maxamet N5s and Para 3 for now. And the Para 3 has been on cardboard duty for more than a year without really losing much edge (there's micro chipping due to how this steel "dulls", but it still cuts very agressively).GarageBoy wrote: ↑Fri Dec 02, 2022 10:35 amDo you know what he normally cuts on a regular basis?

Re: CPM REX 45 | Edge Performance
That's always the problem with testing like this you would need controlled testing to really get a great account of everything that's being cut. Nobody ever commits to memory everything that they cut with their knife. He just cuts everything he needs to cut, we could see by how worn out the G10 is and the patina around the thumb hole that it's getting a lot of use.GarageBoy wrote: ↑Fri Dec 02, 2022 10:35 amDo you know what he normally cuts on a regular basis?

Re: CPM REX 45 | Edge Performance
Thanks for sharing these tests, it's always interesting to see what others put their knives through.
Just sharpened my Rex 45 N5 for the first time last night. I'm liking the steel so far in my limited use.

Nice, what stones, grits, angles, system/no system, how did it burr/deburr and apex?Josh Crutchley wrote: ↑Sat Dec 03, 2022 4:05 pmThanks for sharing these tests, it's always interesting to see what others put their knives through.

Re: CPM REX 45 | Edge Performance
I use an Edge pro with CGS 40, 20, and 10 micron stones. Then I strop on balsa with 5 micron diamond paste. I stuck with the factory angles not sure what they were. Deburring was no problem. It's not hair whittling but sharp enough for my uses.Deadboxhero wrote: ↑Sat Dec 03, 2022 5:46 pm

I honestly need to upgrade my stropping setup. The paste I use is crap from eBay and don't really feel like going through the process with lower grits as I don't get the results I'm after. I've been looking at different sprays to use on leather just can't decide on which.

Re: CPM REX 45 | Edge Performance
Just to be clear, you're recommending 1 Micron right?
