I have a wonderful LeGrelot which was delivered with an edge done with a convex stone. For whatever the reason, it (the edge) was less than great. That being said, I have made a couple attempts to re-do this razor using other (flat) hones. My most recent attempts were a Naniwa 5K-12K progression (so-so) and a Naniwa 5k to Vermont Green Slate finish (not much better). I have used these hones with fine results in the past; all I can surmise is that the convex edge is not allowing me to achieve the results I desire. Is this going to require me to completely reset the bevel and start all over again?
