I read this topic and and saw some interesting things.
A while back I started using linen for the use of my leather strop, and can say that it feels way better to my face.
Saying this and always looking for a sharper edge, which for example can cbn compared with diamond paste, to add value to an even sharper edge?

For example, I now use diamond paste (which is low and therefore must be replaced and I am very satisfied with the paste, but there is always someting better)
What should I buy, CBN or diamond?
Or just keep using diamond
