All those beautiful stones and blades.. Here is am old beater that I am trying to touch up with a Honeyama (koppa). The blade was originally honed on synthetic stones to 12K. It has since started to tug so I put it on the JNAT.

The photo shows the front side I hone on the back side. This is the scratch pattern, photo taken at 2K optical magnification.

I need to watch the scratch pattern more during the progression. I will comment on the shave tomorrow. Any helpful comments.
