Just got my Sage a month ago. It's making its way to being one of my favorite designs from Spyderco. Great size and weight, very fast deployment, equals a very sexy knife. Now I just need to get the second one and wait for the third one.
I love the Sage 1, superb knife. There's something about the thin CPM-S30V that slices like a monster, too. I bought my old man the Sage 2 for father's day. It's extremely nice and slightly thinner than the 1, but not quite as smooth or light. You'll be hard pressed to find a better knife.
