I would just like to share my edge maintenance formula with anyone who would be interested. This method seems to work on most if not all my razors (I have 65 razors).
If a blade is pulling on my whiskers, I go to the 8k with about 8-10 laps, then to the Nani 12k for 4-6 laps, then the 16k for 3-4 laps, then 50-100 laps on the Nakayama Maruichi, then 6-8 laps on the denim flatbed with "Super" Cerium Oxide paste, then 50-100 laps on a flatbed plain bridle leather strop with no paste.
If you want to just tune an edge that is not yet pulling, skip the 8k.
I am sure there are other methods that might work as well or be simpler. This is for the newer guys who might be interested in maintaining an edge that was honed by a pro. A professionally honed edge can last a long time with a bit of periodic maintenance.
I hope others will chime in for the benefit of the newer guys.
As always, start where you need to start and end where you need to end. Honing is a step by step process. Don't burden yourself with too many steps.
