It can be both, years ago on another forum several of us stropped the same razor daily on pure chromium oxide to see when the edge would fail.
It did not, after a week or so all the stria was polished off the bevel and the edge keenness plateaued to a smooth keen shaving edge. After a year nothing changed and many experimenters got boarded and quit the experiment early.
I have a razor candidate that i wanted to try out with the daily Crox on a hanging sailcloth strop. Approximately how many laps after each shave were you doing?
