Dear Gents;
Let me tell you that i have been working this week with Euclid440's system. Its .5 micron CBN on a paper strop, followed by .125 micron CBN on the other side of the same strop. 20 laps on each side every day. My Ralph Aust 7/8 is as sharp as a double edged blade. Or at least feels that way. You will know it the second you put the edge on your face. On top of that is super smooth. After a while you end up with a stria free edge. At first i didnt believe it, but after a couple of hundred laps i took out my daughter's chemistry lab microscope. A 900X magnification does not lie. So far i had zero irritation and zero cuts/nicks.
A word of caution! This is not for everyone. This level of sharpness is very unforgiving. Your technique most be solid. You must not apply pressure. You have to have a serious preshave routine. Good soap. And you have to take your time shaving with an edge this sharp. The reward is worth it. The closest and smoothest shave you can have.
Euclid440, thank you very much. I will keep experimenting. I really like my results so far....
Best regards,
