Getting back to the original topic..........................................
I have one, and it's quickly become my favorite EDC. The CTS-XHP cuts (reprofiles) easily, and polishes to a mirror finish EXTREMELY easily. So far, it seems to keep that edge very well. I personally like it better than S30V, but I've never liked S30V. More than anything, the knives I've owned in it just don't take the edge...for me, the way I sharpen...the way some other steels do. It's a great steel, no doubt. I just don't like it.
I personally like Elmax better...it is a LOT more difficult, for me, to polish than the CTS-XHP, but it still cuts like a frickin light saber and holds that edge very well, on my ZT0551.
That all said, the CTS-XHP is a good steel in my opinion. It's not the be all, end all, but the overall package of the Manix II, it's width (or lack thereof compared to some of my other carry knives), it's weight, how smooth it is, the design, and the blade profile and steel have made it my favorite. Although a knife is in large part the blade and the steel it's composed of, there are quite a few other factors including and in addition to the steel it's made of that make the Manix II in CTS-XHP one of, if not my favorite EDC. YMMV.
