I have a natural combo (blue/yellow) coticule on the way, I have a four-sided paddle strop, some TI white paste and some Hand-American Chromium Oxide powder. I am thinking of getting some diamond pastes and have a couple questions:
1. Since the TI white paste is 10k in grit, would it make sense to go to that off of the coticule?
That would depend on what your goal is. Is the razor shaving well off the coticule ?
2, What would I use between the TI white paste and the Chromium Oxide?
I don't see any need to even go to the CrO. The TI paste is sold as a final polish IIRC.
3. Would a diamond paste, negate the coticule smooth edge?
It would depend on how you use or abuse the paste & as I said before what your goal is.
I suggest you isolate your experiments to a single paste before using them in sequence . If your edge is good off the stone you may find "less is more."
