I have a combo edge S110V Shallot, probably my favorite of all the Kershaws I own. I've used it some, mostly around the house and a couple times at work. It still has that factory edge, slices paper without tearing it up. It's a great little knife IMO and would buy another one if it was available for a reasonable price. I polished the edge on an S90V knife and was sort of disappointed though, it was crazy sharp for a while, then it just kept a working edge. I resharpened it, removed the polished edge and left it at 600 grit, it performs much better. Holds a really good edge so far, haven't had to touch it up at all.
Edit:
I'd love to see more RJ Martin designs in any high performance steel. The Overkill would be a winner for sure

Make it happen Thomas!
