That's kind of what I was thinking too r8shell... that particular knife though does not appear to be used much at all and came in original box with the papers rarely unfolded. I wonder if they would have added some type of protective finish out of the factory? I don't want to try to scratch it off LoL...Here's my wild guess:
The outside of the springs are dark because they are carbon steel and come in contact with hand sweat. The inside is still shiny because it gets a film of oil from when you oil the pivots, and that oil doesn't get rubbed off as quickly as on the outside.
