Bead blast that baby. Strip it down and do each part separately.
I love a bead blast look on handles and clips. This Stinger of mine used to be black. Not anodized for a finish but I've stripped anodized titanium and aluminum also using my bead blaster and glass beads and they will look similar to this when finished.
BTW, Dirk AKA OUPA, did the New Zealand Pau Shell inlay on this one and it is a righteous job too. I love this knife. I got it in a trade all scratched up. So the only solution was to tear it down and bead blast it. Now the scratches cannot even be seen.
