i've sharpened a lot of knives on a sharpmaker and i havent scuffed up any of them, FWIW, ya just have to be carefull.
i have plenty of knives which arent scuffed/scratched up, i dont cut stuff with mine which will scuff 'em up, i have a utility knife for that, the ones i carry primarily for SD dont see any utility use thus they dont get scuffed up.
i can understand the guys frustrations, i have never been the type to think scuffs give a knife character or any of that BS, to me a scuffed up knife looks like, well, a scuffed up knife lol, it certainly isnt a added bonus, YMMV though,
so sure its possible to carry one daily and the blade not to get scuffed up, even if ya use them, i carry a spyderco delica SE for utility and a emerson specwar CQC13, emerson CQC12 or a spyderco ti ATR strictly for SD, and because i collect knives and enjoy packing a nice one.
as far as removing a scuff, i suppose any good 'smith could do that as long as its not a coated blade, ya just have to buff it out. is it worth it to send it off to get a scuff removed? i scuffed the blade on my crawford perfigo and did just that, i dont know if i'd do it with a production knife though, would just depend.
