My understanding of micro-shipping is that it is a chip in the blade's edge that is noticeable under magnification, but not with the naked eye. As the magnification increases, so does the observable presence of micro-chipping. So I am wondering if we can arrive at a consensus where if the edge as viewed, if continuous, might be said to be ready to apply to the face.
From my experience, I would place it at 10x, as viewed with a Bausch & Lomb Hastings triplet loupe.
