i carry a lot of ti handle knives, ie crawford ti kasper, perfigo, emerson CQC12, strider SnG, SmF, spyderco Ti ATR, and they will all scuff, to one degree or another with use, imho the stonewash ti (ie spyderco Ti ATR and EKI CQC12) is fairly tough, bead blast scuffs easily as does the flamed strider Ti, and anodised ti scuffs (and shows scuffs) worse than any imho. and the anodising makes the scuffs show up worse too, imho,
i do like ti for handles though, even with the scuffing, its just something ya learn to live with, not like, live with, i'm not one of those who feels it adds character or anything, to me it just looks "scuffed" lol.
but i just like the look and feel better than G10 or micarta.
FWIW aluminum handles scuff easier than ti, i have a lot of experience with anodised aluminum handles as i used to collect microtechs and i can assure you they scuff easier than ti, also have a SS spyderco ATR and it doesnt scuff bad at all, i guess the stonewash finish combined with the harder SS makes it as close to scuff resistant as any metal handles i've seen, again, it will scuff though, just not as easy as ti or alloy will.
