i have a simply calphalon nonstick pan.. it's 2 layers nonstick and hard anodized exterior.. when i was cooking one time, i accidentally hit the surface with a steak knife ( trying to turn over something, being very careful not to touch the surface [but it did anyway!! i know i know... it happens all the time]. it scratched a very lil bit which is not even an inch at all.. should i try to return this? because before this happened there's always food residue that's hard to come when i clean it.. but you see i don't wanna pay the cost for shipping if it's worth 30 or 50 and they won't replace it.. if i decide to continue using this, is this still safe to use? i don't really see any flakes coming off.. it's hard to tell coz it's black and the way the nonstick looks like, it's not shiny at all, unlike my any other regular nonstick pans.. why is that by the way?? thanks for reading and i deeply appreciate any advice..
