I have two models of them. They take a great edge, and are fairly easy to sharpen. To me, they are great camp/glove box knifes. I am sure one of the more tech minded guys here at the forum can tell you the actual difference in the steel properties, vs. one of the more expensive steels, but for me, it is a great knife to have around for anyone in camp to use, and not have to worry about one of your more expensive knifes being misused. I am sure they don't hold an edge as long as say a ATS34, or 440v, or D2 knife, but plenty long enough, and like I say, they sharpen up great. I like them.
