It is important to remember that you don't shave under 30X, and sometimes a blade can look pretty rough at 30X and still shave fine. I chipped a blade on the faucet months ago and completed the shave with it without an issue. I personally use only a 10X loupe and have gotten great shaves with blades that had micro-chipping apparent at 10X.
