I've been using a 710HS as my EDC for almost a year now, and I really mean every day. I have yet to find any knife that can get me to take it out of my pocket and carry something else. M2 is the best blade steel I've ever used, to be fair I haven't used most of the high grade stainless steels out there, but I can't see them beating M2 in anything but stain resistance. I've never had any problems with rust on it, it holds an edge like it has a deathgrip on it, and it's tough. I find it touches up very easily, I spend maybe 10 minutes sharpening every 2 weeks, and that's using it every single day. One of the great advantages I've found with M2 is that it can handle a very thin edge. My 710HS has a convex edge that blends right into the primary grind, which makes it an incredible slicer, but it's still tough enough to handle some pretty hard use. I'd reccommend reading the article by Joe Talmadge on making the 710 perform better, he gives some really good advice.
