I can't help you much with steel comparisons, but I had an Axis AFCK and I traded it with another forumite for a 154CM 710. I am glad that I did so.
To start with, the AFCK was a fine knife but it just wasn't for me.
It didn't carry as well as the 710. Although they have about the same blade length, the AFCK seems much larger in the pocket due to the long, pointed end of the handle. I suppose this is there for jabbing people or things, and it would probably work very well for that purpose, but in my case it just got in the way.
I like the handle on the 710 much better for general use. The AFCK has a very deep choil and a severe drop off at the end of the handle. I found this basicly forced me to use a single grip if I wanted to be comfortable. The 710 is much more utilitarian, just a moderately curved rectangle with some slots for extra grip.
I preferred the blade shape of the 710. Slightly pointier and seems thinner at the tip, with just a hint of a recurve.
My impression is that the AFCK is a dedicated self-defense knife while the 710 is a much better everyday user. I have yet to encounter a knife that is as good of a general use cutter as the 710.
Of course, all of this is highly subjective. Really they are both excellent knives.
