I haven't tried the WSKO with anything more 'super' than CPM-S30V. It worked very well and rather easily on that though. I'd expect S110V to take a good bit longer, but should work great. I freehand with the WSKO, which I think provides a lot more control.
Definitely practice on some other knives first. Old abused kitchen knives can be very instructive, though the more abused they are the longer they take. Good luck!
