Now I'm new to this single bevel mania, but I like the reasoning. I've bought a few different types and just couldn't get them to my (nut case sharpenough) likeing, untill now. I just did a ABowyer 11/4" up on a KME and large Diamond stone. I ground them on the face side to a fine polished edge but still it didn't quite have that rubber band nicking edge. Then I flipped the head over and in about five pushes on the none cutting side put a tiny edge. Pow goes the rubber band. It's so slight you'll never effect the spliting action but it gave it that razor sharp edge I like to feel, just my two cents. I'm not sure how it will work on a convex edge single but I have some and aim to find out.
