I appreciate your useful information. I confess it wasn't the answer I was hoping for but thank you for the honesty!

So, does that mean that the wiki is wrong when it says that a 3.0 micron paste is the same abrasiveness as an 8k grit? I read on here that an 8k stone is enough for doing touch up honing, so if the 3.0 micron paste can't do the same job then either...

1. The 3.0 micron paste isn't the same abrasiveness as an 8k grit like the wiki says.
2. An 8k grit isn't in fact enough for touch up honing.
3. I'm missing something.

I'd be interested to hear your thoughts.
