Strop Substrate for .1 Cerium Oxide or .125 CBN 120K

What substrate to use to strop with Cerium Oxide .125 CBN 120K? I seems anything I use will be more coarse than the paste.

I am experimenting with a progression of .5 Dia, - .5 CrO, - then the .125 CBN or the .1 Cerium Oxide. Just trying to tone the blade down a bit.

I really hope I can get this to work. I really don't know which would be better, the CBN or CeOx? Would they work on a paddle felt, how do you mix them?

So much detail these days, what would or forefathers think? They probably got better shaves than we can with a rock and a razor....:)

Thanks, Dave

For your .125 CBN, glue a piece of blemish-free leather onto a ceramic tile or thick balsa wood. Then spray the leather lightly with the CBN. Should work well as a bench strop if you spray CBN LIGHTLY.
