Over honing is different from hone wear. Over honing is honing until the edge gets very fragile and fall apart. Hone wear is from using to coarse of a hone and to much pressure, many used razors have this as they didn't tape the spines like many of us do when honing.

Here's a good link with pictures that show hone wear
