I'm using my Chinese Waterstone as a finishing hone, and now because it gives me a smoother shave than my chromium pasted bench hone, also a refresher stone. My question is, barring any injury to my razor's edge, how long is it possible to go before I need to use my Norton 4/8 again? I mean if the bevel is set and my shaves are bbs, why would I need to? Will the time come when my bevel wears and needs to be reset? Just curious. I know that on my knives, once the initial edge is put on, only an occasional run on a steel or ceramic rod is needed to bring the edge back to snuff. It's usually not until I take out the edge on a bone, or something that I ever have to rehone my knives.
