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

Superior work as always Jim! Thank you very much, your work is my reference!
Please have a look on CPM-M4 as mentioned ;-)

best regards, and keep always sharp

Mr. Ankerson, would you say that it is a safe bet that the companies have the HT worked out on the Elmax? After some lackluster reports early on, it seems like it's pretty nice steel. Curious as to your thoughts.

From the samples I have seen lately they seem to be doing fine.

I would like to see where CPM 4V or Vanadis 4E would fit in. Probably somewhere between CRU-Wear, Z-Wear,PD1 class and M4.

I am sure I will get around to testing 4V some day, still have to cut with ZDP-189(65) and CPM M4(62.5) on the coarse edge section.
 
Are you aware of any productin 4V yet? I am guessing a 4V Mule will be coming soon. Big Chris has some 4V blades out there.
 
I've got to ask since you have S30V listed at least twice, were any of those Benchmades, and if so did they fall into the Rockwell hardness category of 58.5, or 60?

Jim, Bark River is making a hunter in 4V @ 59-60.

From my testing so far 59-60 is about 2 to 3 points softer than 4V can be ran safely.
I have not batoned hard yet, but my test knife at 63 Rc is a 5" blade at .012" behind the edge with a 24 degree inclusive edge.
I have not done anything to the edge yet that half a dozen strokes on an extrafine DMT and stropping would not cure.
4V is a great steel with very good qualities.
My point is that 59-60 Rc is not prime hardness and is not going to score as good as possible.
