I didn't want to drastically change the overall look of the knife. So after some testing on old titanium:
An aluminum oxide blast gives you a mediun gray look as the Sebenza looks......too drastic!
A flame treatment gives you a nice bronze look..........not bad, but still glossy.
A sand blast is too aggressive.
I used 80 grit glass beads, they didn't "take out" the Striations as sand would have. Basically, it knocked off the gloss/glair, gave it a dull very light gray look. perfect! If you held two knives together, you would see the diff, but alone not.
