nick in the charger :/

so today I was unwinding the charger for my 13'' macbook..and it accidentally spun out and hit something. Now I see a small nick in the metal if I look closely. (i tried to get a picture of it but my camera sucks) The charger still works, it's charging right now..but should I be worried that it will mess up in the long run or something?

No - if I understand you correctly it is just a cosmetic nick through the coating on the charger body.

If you're talking about the metal part facing the camera in this image (not my magsafe)..then cool

So this nick, it's not a bump OUT that might prevent the pins from contacting.. if so.. and it's still going to sit flush (and it'd have to be a pretty big bump to be honest), then you're cool.
