This is true. There were more spots on the rough parts (such as striated the grind of the blade, and the etching), although one bad spot on the polished spine (this was luckily easy to get rid of). My DD razor that I compare to has a more polished blade throughout. But this is not true for my other razors though, as they vary quite a bit.
