After a level of acceptable sharpness, is smoothness inversely proportional to sharpness? For all hones? If that is true, can we just do a bit of toning down by dragging across Denny's wet horn ( oops

: ) or a cork? Or, just increase the bevel angle? Or, both? Do over-sharp/too-thin edges cut hair worse?
I would think efficiency for sharpening would be a good thing if you can control it.
Those are very valid questions, George. What makes an edge
smooth?
I don't know. But I have a couple ideas.
First we need to answer the important question. What is that:
smooth?
If an edge doesn't cut the beard well, people will say that it's not smooth, for the reason that it pulls at their whiskers. It will also likely invite the user to apply more pressure, which will have a detrimental effect on the skin. That too will add to an experienced lack of "smoothness".
On the other hand, when a edge is too sharp, it'll cut through whiskers without pull, but the user may feel how it damages the outer layer of the skin at the same time. He will likely find the shave "not smooth". "Harsh" is another term often heard.
What this demonstrates is that a lack of smoothness does not always means the same thing. The first thing we need to do, it come up with a properly defined set of terms, so we can communicate in a more exact manner.
But regardless how that linguistic problem can be solved, the question is also whether a good edge is merely a matter of the correct keenness? Or is them something unaccounted that can make one equally keen edge smoother than the other? Something that is offered by the way a hone cuts, the shape of it abrasive particles, their hardness, what binds them together? The answer is probably yes on all acounts, but at which ratio?
For the most part of my experience on Coticules, the keener I could make my razors, the better they shaved. It was (and is) that simple. A while ago, I discovered something that allowed me to push the keenness barrier on a Coticule further than I ever could before (the soap/wax/shellac trick). And I found edges that were starting to show signs of harshness. That provides empirical evidence for something I've always accepted as obvious: an edge can be keener than good for my shave. I've made the "too keen" statement about the Naniwa Chosera 10K as well, but one could argue it was the result of an "unaccounted difference" between Choseras and a Coticules. But now that we can also get too keen off a Coticule, it's a proven fact: edges can be to keen (for my taste). Not too "Chosera", or too "Escher", just: too
keen.
And that brings us seamlessly at your very interesting question: can the too keen edge of, for instance, my Chosera 10K, be made less keen to resemble the perfect Coticule edge? It think it can be done, and the "unaccounted hone magic" might turn out be just a metaphor for that what has not been explained yet. Something that doesn't exist in the end.
But why bother with mimicking the perfect edge, is I already have a hone that offers me just that?
