Sorry if I'm rehashing questions that have already been asked. My previous reference--the "Coticule Chronicles" was mostly lost in the crash. Having read it, though, here is my question: the only stone I have is a combination yellow/blue coticule. When I bought it, the advice I was given was that I didn't need a Norton 4k/8k if all I was going to do was touch up razors that already had an edge. This is the case as my few razors were purchased new and then honed by a honemeister or purchased on B/S/T and advertised as shave-ready--which I do not doubt. Is there a pyramid progression as with the 4k/8k that should be followed with the coticule, should I just hone and test on one side until I feel it is shave ready? I am very new at this and am looking for a base guideline so that I can learn. Thanks.
