Unfortunately I don't have a microscope or even macro lens for my camera, so these are the best I could do with the 18-55 kit lens and a tripod.

This blade is extra hollow, so I didn't want to remove more pitting than I had to. After getting the rust off with 400 grit paper I went to the 1k Norton. Photographed is the heel with a very small chip. I cannot tell with my naked eye whether the chip is at the end of a very small crack that is less than a mm long or maybe just some pitting on the side of the bevel that will hone out with just a little more work.

Opinions from the peanut gallery?
