Until there's a simple, consistent way to "test" and compare edges, IMO, all the discussion on sharpening technique is a waste of breath.. Mike Tobey and I went down this road a few years ago, trying to devise a method by which we could measure the "sharpness" of a blade, and it proved to us that there are just too many variables for an individual to accomplish this task..altho it can be done in a lab.
I personally much prefer using power tools to sharpen, and I can do a very good job of it freehand on stones and leather also, but I can reduce the time it takes to get a really good edge to a matter of seconds, after the bevel is established...I tend to think of a buffing wheel {leather or muslin} as an "endless flat strop" charged with an extremely fine abrasive, and a mirror surface can be achieved very quickly, once the freehand technique has been learned. I dont worry very much about "flat"...I worry about "sharp"!!
