I think you missed my point. But if I understand you correctly, you're trying to make the point that,
all things being equal, the relative attributes of a natural waterstone lend it to 'deburr' in a more efficient way than a synthetic stone.
Maybe what I'm trying to say is that I feel the most important aspect of sharpening isn't the tool you're using, but simply how you're using it. Furthermore, just based on my experience, friends and those I talk to who purchase stones under the impression that the stone contains a special attribute, a characteristic that will somehow imbue their knives' with superior edges, usually end up disappointed by the end results.
Anyway, I think we should agree to disagree. I don't want to drag this off-topic. (unless the discussion is fine the direction it's going
)
