Congratulations Phrank nice Special stone, they are awesome. Only use on Good Razors he,he.
Here is big Yoncho-gake Henkotsu bevel set process.. One trick on wa-kamisori is to use is tape on Omote side to strike new edge and see how the spine geometry will be affected. Yes the Chosera 1K is used for this, why mess around.

Once you are confident the grind is evenly balanced you can remove tape or leave on. I prefer to remove tape unless requested not to. Make however many strokes it takes to set the bevel proper. It will not take as many on the Ura side.

Visually inspect to assure the bevel is set before proceeding to the finer stone progression. to be continued. Mike
