Interesting thread. I recently set my personal one razor record - 20 days - when I was trying to master a Feather non-folding clone (CJB) for a week and then taking it on a trip.
No issues with the blade since I could change it, but it was an eye opening experience that made me want to try it with a "Regular" SR. Since my last trip I've been shaving with one Razor, a Robert Williams Purist, every day. I've just learned that for me when I try something off the reservation (Feather & Purist are not like any of my "conventional SRs") I'm better off using it every day until I'm comfortable with it.
Do either of you use or plan to use anything to "refresh" the edge? (Pasted Strop of some kind)
