I don’t understand that concept either Mr. Steve. Once the edge is ground to the edge, continuing to unnecessarily grind more just removes more steel than necessary. If the knife is tapered from spine to edge, then removing more metal will take the bevel more toward the spine which may increase the width of the bevel. But if the sharpening angle is the same, so will be the bevel angle.
Obviously more sharpening will continuously create burr, but as long as the edge is evenly ground from each side the burr should be no larger than with less sharpening. The trick is to just keep flipping the blade so that newly formed burr is ground off as you go so as not to create some big gnarly burr that is difficult to remove.
If you keep grinding away, eventually the blade will be nothing but a toothpick with a sharp edge, but I don’t see how forming a completely new edge could possible make a blade less sharp.
If you really think about what is happening when grinding an edge, the idea of over sharpening makes little sense, other than it shortens the life of the blade by reducing the number of times it can be sharpened.
I think you are a far better sharpener than you give yourself credit for, or you wouldn't even be asking that question!
