Seems like if some guys can keep a razor going for quite a while on just leather,
and eventually go to a pasted strop when that no longer works,
and then to a barber's hone or other finisher when that fails,
and then back to an 8k,
and then...etc.

I mean, I reset bevels more often than I need to on some of my beater razors just for practice, but for someone who knew what they were doing, unless they dinged the edge or something, they could probably go almost forever before truly resetting the bevel.
