Another +1 on Chris, I bought a CPM-10V kephart fixed blade from him, and he's just about finished a custom order I designed and he's bringing to life in CPM-3V. I plan to have him make me another 3 at least for me as well in steels very few will work with (bushcraft in 10V, Drop point in S110V and Chopper in 3V). The Kephart I already have from him came extremely sharp, with a very comfortable handle, excellent quality.
As far as the steel you mentioned, I'm guess you mean CPM-S90V, of which there is quite a bit of info around here on it, but as for the basics, its a very high wear stainless, very few production knives are made with it, almost all that have have been short sprint runs by spyderco, although they now the Spyderco Phil Wilson Southfork as a regular production knife (also on my list of to buy knives). It will be difficult to sharpen, but it will hold an edge a very long time, (longer than M390, M4, ZDP-189).
