Ranking of Steels in Categories based on Edge Retention cutting 5/8" rope

The first couple of "hard use" knives that I made in 3V, I guess I didn't know any better so I just automatically took the edge down to .020 and had Peters harden it to 60Rc.

Make a 3V knife for yourself and have it heat treated to HRC 62. I think you will be surprised how well the edge holds up to abuse.

Chuck, I was actually thinking about having that done in high temp salt so that maybe I can get at least one of those points of hardness for "free". Could be interesting. ;)
 
I will be shipping mg 4V knife to Jim on friday.

Excellent!

Yep. I'm looking forward to seeing how it does. It should be a very good performer. I first heard rumors of the steel several years ago. It's nice to see it finally appearing in the hands of knifemakers.

Sal has been running the mules pretty hard. I doubt it will be full hardness like you can get running one at a time in a good setup but they won't be but 2 to 2.5 off at the most. The Cruwear was rc 62. The Super Blue same. Heck, the 52100 was 62 as well. I forget what the CPM M4 was but the Bradley first run came in almost rc 64. One of the many reasons I feel we have been treated very well by Sal in the Mule team program. It's been great!

I thought they even had one or two that nearly hit 65RC? On the Bradley I mean.

K390 Mule team on order...

Just ordered mine a few hours ago, I am eagerly awaiting the results of the testing! I have heard phenomenal reports on K390, and hope it's as good as it seems from reviews and the composition say it is!

Now I'm hoping against hope that there isn't another botched batch like the Cruwear Mule (No knock to Spyderco there, they show amazing consistency in their quality, and handled the re-release like a champ).

That's another one that surprises me. I thought it would be much higher. BG42 is very wear resistant stuff. It looks like this new stuff isn't even as good as it's predecessor in the wear resistance department. That's interesting. Thanks for running both tests too Jim. Always interesting stuff.

It did well with a coarse edge, pretty much right where it should have fallen, polished edge was pretty predictable.

BG42 was always pretty wear resistant especially getting north of rc 60 to 62. It doesn't have the numbers of some others but it had performance as noted by the charts latrobe used.

I know manufacturers sell steel but I found these charts to be pretty accurate IME. At 60-62 I always felt it was above the VG10/154cm/ATS 34/VG1, even S30V@ rc 59 levels of wear. I should dig you out one of my old Buck customs in BG42, or find someone to lend a BG42 millie for testing. They should place higher than the B75P did. The B75P is a powder steel variant. I know it helps toughness but does it reduce wear resistance at the same hardness?

Interesting.
