I was wondering if anyone could shed some light on this. I have a blade that was pro honed early this fall. It is a really smooth shaver and I had been using about once a week. I recently discovered some rust on the toe and tang so I looked at the edge with my pocket microscope. There is a black spot on the edge near the toe. The spot appears to be a small crater on edge but different from other chips I have seen. The area is black and the chipped area does not have a distinct border. It is not reflecting light like a fresh chip.
Is the edge damage rust, or a chip, or maybe a folded edge? I wiped edge off and stropped the razor on my old nylon linen and the blemish is still there. Does anyone have a clear idea of what is going on here? Or maybe pics of different types of edge damage?
