Well done and Bravo, Stefan.
Question: I gather from your description that you're not using slurry from the honzan in the final (pre-water) step, but rather you're creating the last slurry from a (tomo)nagura that may or may not be related to the honzan - in this case, not. Is there a reason that you didn't raise this last slurry directly from the honzan? In other words, why use a tomonagura
softer than the base stone in the last slurry step?
Again - great job!
