Yes.
The stone cost is because I got a little stupid, I could have stayed with a basic three stone set-up and been fine. Well maybe with 1 800 and just 1 nautural....
Scuffing is part of learning. There is a sentiment here to practice on cheap knives to learn so that one doesn't "ruin" good knives. I think one would have to do something very wrong for a very long time to ruin a knife. I've started digging that hole and when I realized I should stop digging I've sent knives to Jon, DaveM and Korin to "unruin" them. I would still send off good damascus for thinning but that's just knowing my limitations.
And knowing how to sharpen has some value in and of itself. I take diamond plates to deer camp, s&g's to friends kitchens (if asked) or take friends knives home with me. And can leave them sharper than they were.
