Why the 40° edge will not score as well as the 20°

[KnifeGrinders]

Thanks for bringing this up again Mr. KG and pestering the point.  While I have done no experimenting to verify it, I think that without giving it much thought at the time I have actually noticed that more acute bevels seem to end up sharper than those less acute.  I can’t say for sure, but I have that gut feeling and it’s an interesting hypothesis.  

Knowing your amazingly exhaustive methods, I suspect that you would not have even asked the question without prior extensive experimentation and data.

Am I correct in my assumption?  For instance, considering you’re finely honed sharpening expertise, do you find difficulty in getting a 20 dps edge sharper than near 110 BESS?

First, SHARPCO started me thinking of this when he asked me whether it is possible at all to hone a 20 dps edge to 50 BESS. He was frustrated he could not.
About the same time there was a thread by Sirano on this forum that he could not get any decent BESS, sharpening a blade with steep edge, some dagger.
Back then I hardly ever sharpened knives at 20 dps. But I often sharpened folders at 15 dps, and could tell straight away that they never score as well as the 12 dps, let alone 10 dps edge, despite showing the same keenness in the HHT test.

I simply kept registering all these occasions in my memory till could see the above pattern.
Naturally, I also kept thinking of an explanation for this.

I am looking for confirmation from others of the "best score by edge angle".
But probably I better ask at the Tormek forum, as there is over a thousand using our software for grinding angle on Tormek, and among them there should be many who also have the BESS sharpness tester.
