This is more about titanium than the Sage4 but the Sage4 is the only knife I've owned with titanium anything. The bolsters are getting very visible scratches that I can't imagine where they are coming from. I treat it the same a any knife with metal exposed on the handle and nothing else scratches as easily as ti. This is not a complaint, just an observation as well as information for someone considering a knife (or anything) with titanium. Personally, I like the "used" look. Seems to add character.
I would like to know the best way to remove the scratches out of curiosity. I had read ti scratches easily and some have removed the scratches and I'd like to know how just in case I want to remove them. My first thought is to use my Dremel and grinding bits. Not really. I was considering some steel wool. At this point I don't know why I would remove them because new scratches would replace them quickly.
