Sweet Fallkniven and great quote in the OP post!
My take on sharpness has changed over time. Used to strive for insane sharpness--as sharp as I could possibly get it on every knife. Now have become more practical because of time demands. With most folding, small fixed, and kitchen knives, I aim for a level of sharpness that would equate to the 'shaving sharp' standard described in the sharpness chart in the maintenance forum. While at the same time, being a 'durable' and sustainable edge. This is not smooth shaving capable of shaving your face with very low friction like a razor. But more like able to shave arm/leg hair with light scraping friction, and able to cleanly slice thin cigarette paper lengthwise. Edges at that level of sharpness are more than sharp enough to easily do everything I need on regular user knives, and I can achieve that level of sharpness very quickly, often on a single stone plus a strop. But still, sometimes I'll take one of my knives and spend a couple of hours, and get it as extremely sharp as I can get it. This is mainly just for fun, and because in the process of doing it, you learn more about sharpening nuances and it keeps improving your sharpening skills.
