I would certainly listen to Brad and Glen here; make sure you are using a loupe or some type of magnification when you do these kinds of questionable blades. That pitting may not stand out like a sore thumb, but still give you grief none-the-less. Since you did breadknife the blade, go to youtube look up gssixgun's video on breadknifing a blade, watch it til' your eyes bleed then attempt another bevel set after checking the edge under magnification. Those videos helped me immensely; heck I even did the whole thing WHILE I watched the videos just to be sure. Just a suggestion.
