It's G-2, not J-2. It's normally left a bit softer than steels like ATS-55, which Spyderco is using now, and G-2 doesn't hold an edge quite as well, though it should be a hair tougher (I'm not sure if that's really the case though, I'm having a harder time busting the point off my ATS-55 endura than I did my g-2 models, which all have busted points). G-2 seems to be more stain-resistant. All in all, I've considered it a fine steel, but a step down from ATS-34 as far as general-use folder steels go.
