Every three to five minutes, all day, which is the actual rhythm
The rhythm
Twenty strokes with the stone every three to five minutes of mowing. It takes fifteen seconds and it is what makes the whole thing effortless.
Peening
Every eight to ten hours the edge is hammered thin again on an anvil. Honing maintains an edge; peening recreates it and cannot be skipped.
What good feels like
The blade should hiss rather than thud. If you are pushing, it is blunt, and pushing harder is the wrong response every time.
