Well, 440C is an excellent stainless and many top makers still think of it as a very good steel for their using knives. It takes and holds a good edge and is very rust resistant.
It is much harder to sharpen than CV but with the right hones you'll be fine.
Here's an old excerpt from Joe Talmadge's Steel FAQ:
440 A - 440 B - 440C The carbon content (and hardenability) of this stainless steel goes up in order from A (.75%) to B (.9%) to C (1.2%). 440C is an excellent, high-end stainless steel, usually hardened to around 56-58 Rc. All three resist rust well, with 440A being the most rust resistant, and 440C the least. The SOG Seal 2000 is 440A, and Randall uses 440B for their stainless knives. 440C is fairly ubiquitous, and is generally considered the penultimate general-use stainless (with ATS-34 being the ultimate). If your knife is marked with just "440", it is probably the less expensive 440A; if a manufacturer had used the more expensive 440C, he'd want to advertise that. The general feeling is that 440A (and similar steels, see below) is just good enough for everyday use, especially with a good heat treat (we've heard good reports on SOG's 440A heat treat). 440-B is a very solid performer and 440-C is excellent.
