I recently purchased a Shapton pro 15K stone. I used 1200 grit wet sandpaper to "lap" it like I have for other stones. When looking at it at an angle toward a light it looks to be mirror-like as I would expect.
When I run a blade over it, it does not have to smooth feel of the Norton but rather feels a little "bumpy" where I expected it to feel as smooth as glass.
Is there something I am not understanding?
I have also noticed this with other 12K stones as well.
Anyone have any observations or advice before I make another try?
