Of course you are right about the steels used by CRKT and the Chinese brands, but again - everything below D2 in the Chinese knives is nothing so much better than the 13Mov used by CRKT. They might be good, but nothing exceptional or close to S30V for example, that goes in the higher end of the Chinese knives and they are much more expensive than the higher end of CRKT ( in question)
I'm also following Stassa 73, his tests are fine but I much prefer more scientific approach. They are good for those steels but for something at the higher end, I wouldn't look at the Tube for "facts"... I would look at Larrin's info and will compare it with my own experience with particular steel, this is the only correct comparing in my case.
Steel performance really does matter and the "everything below D2" can be deceptive. While D2 on a Benchmade or a custom knife can have great edge retention, that usually isn't true of a lot of the Chinese D2 used in budget knives. While the worst Chinese D2 tends to be noticeably better than the best 8Cr13Mov, it might not out-cut 14C28N, 9Cr18Mov, or other budget steels that people view as "below D2".
This is where I've taken issue with Larrin's recent ratings. For instance, he rates 8Cr13Mov, 14C28N, Nitro-V, and LC200N as equal. While that might be true for his ideal heat treatment in the specific testing environment of CATRA, that is generally not true of actual production knives with their real-world heat treatments under a variety of normal use conditions. We can see similar issues with 440A being rated higher than any of those steels, VG-10 being rated higher than BD1N, or the scale of difference between any of these steels and say, D2.
Here are a couple of videos from that tester I recommended. I described his particular test conditions previously. His results are statistically repeatable and largely in line with my own experiences. Notice that a few of the knives here are loaners from me. My Naja in 9Cr18Mov at 60HRC showed edge retention on par with the low end of various "super steels".
The second video discusses the poor performance of several knives in Chinese D2.
