I have one with the 70/30 edge. Very sharp and stays that way. It is a very small knife, so the thumb stud opening can be a little awkward on occasion.
However, I have grown to HATE the CRKT heavy bead blast.
If you can afford a few dollars more, I think anthony cheeseboro (a fellow forumite) still has an S-2 small for sale (very old post). I bought my medium S-2 from anthony and am very happy with it. It has more like a "frost" bead blast, more like a satin finish.
