Thanks Cliff, that is very interesting.
An ave 66% increase in edge retention between 15 vs 20 deg is quite dramatic.
If you had to make an informed guess, what would be the low range on the micro bevel angle for high carbide steels like S30V / S90V for light duty every day carry use?
I keep mine at 15 deg and they seem to hold up well enough for my typical light usage.
