Smegmalicious you're confused about how hones work. With the exception of diamond hones, it is critical for the surface of hones to break down in order for them to present fresh, sharp grit for honing. Waterstones are designed to break down relatively fast when wet with water. Oil stones break down a bit slower than waterstones, but using oil rather than water. Ceramic hones are used dry and wear down slowly, hence they cut slowly. When you clean them with abrasives, which is the normal way, you not only remove debris from the surface you also loosen up and slightly roughen the surface. This just restores the surface to closer to its state when it came from the factory. The ceramic is so hard and resistant to acids and abrasives that you are lucky if you can knock the shiny glaze off the surface of the stones. You don't threaten the overall strength or contours of the rods. You just make the rods work better. That includes the ultra-fine grit rods.
