I own several CS knives and for the most part find them very well-made. I especially find the clip-pointed blades on their Voyager series to have excellent geometry and finish, my fave of those being the X2 Voyager. I also have a well-made Scimitar which has one of the more reliable and tough-to-unlock linerlock mechanisms I own, and awesome edge geometry.
I don't own any of their Carbon V knives, and own only own Taiwan-made CS knife, a Kobun. I have a friend who uses one of the older, Japan-made Kobuns in AUS-8 and his is much, much nicer. But mine is okay for what it is and I've not had any edge problems with it; it just looks cheap in comparison, what with the bead blast, etc.
