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

Ankerson, the CTS-BD1 and 5160 results are a bit strange..
How would you explain the poor performance of BD1? The 5160 with less carbide forming elements and a very low 55 HRc is in your higher group. I would expect the BD1 being there and 5160 being the lowest of all.

Or am I reading your results incorrectly?


Also, Im sure Im not the only who would be very interested in CPM-3V :)

That's not really poor performance, BD1 is a budget steel and I am not sure what the hardness was so it's right were it should be from the testing.

5160 depends not just on RC hardness, but also tempering so there isn't really any absolute with that steel.

I could test 3 identical blades at the same HRC, but tempered differently and all 3 would perform different.
 
No worries then. Based on the element composition and the result I'd expect the CTS-BD1 with proper heattreat at the same level with AUS8 and VG-10. This result seems as if the HRc is below 59 which is low assuming your knife was from Spyderco. I can't say I agree about the budget steel, I couldn't find anything to support that.

What really surprises me is a 5160 steel in 55 HRc performing that well. Regardless how well the HT has been done, 55Hrc among 59Hrc steels is unexpected at least to me. I'd be really interested seeing Dozier's D2 tested there. Would be nice to see just how well it would do in your tests. :thumbup:

You are stretching a bit there...

We won't know until production blades start hitting the market then they can be tested and checked for HRC to see were they are running them.

The blade I used was a Mule and I am not sure what the HRC was.

Being it's a Chromium steel with almost no carbon it will need to be at a high HRC to hold if they can get it there. (Think ZDP-189 here, except ZDP has enough carbon to really run it hard in the 65+ range)

Not sure how high it could really be run before problems would start as it's not really available as of yet.

Time will tell if makers start using it.
 
As time goes on, I'm enjoying the few knives I have that are not stainless but "high" carbon. Is SR-101 (52100) a high carbon steel? I like the way it takes a forced patina.

At the moment, I'm considering getting a damascus blade made of 1095 hardened to 58-60 HRC. Would you expect that to be a decent performer in terms of holding an edge? Where might that kind of blade tend to lie in your rankings?

52100 is high carbon, I think it's 1%.
 
Was just wondering if that h1 was a fresh blade or an old one . As I have heard of it work hardening over time and sharpening
 
Would like to see u put that h1 to work hard for a couple months. Then comeback and test it again and see if there is any truth to this work hardening thing.

I strongly suspect that work hardening is only noticeable after significant metal removal, and specifically pertains to grinding with power tools.

Mine wasn't particularly difficult to reprofile, like grinding a bar of butter really;).
