Revitalizing stag and damascus

[ohen cepel]

I have an older Buck factory custom 110, stag handle and damascus blade. With use and age the contrast on the damascus has deminished a lot and I would like to bring that back so it looks more like damascus. Best way to do this?

Also, the stag is showing its age and doesn't have much character to it now. Best thing to maintain that as well as possibly bringing some of the former color in it back? Even if that can't be done, best thing to maintain the stag with?

Thanks in advance!
