Query: Edges like an aluminum can

I'm returning this pan to Calphalon. I have an entire set of CS Nonstick, which Calphalon says it doesn't make anymore. So, when I returned one of my CS pans to Calphalon for a warranty replacement, it sent me a Contemporary Nonstick. It is FAR worse than the CS, which is stainless steel and dishwasher safe. This one is aluminum and not dishwasher safe. In hand-washing my new pan, the edge of it sliced open my finger. On closer examination, I realized the the edge was not smooth and clean like my CS; rather the edges were like they were cut by a can-opener: generally smooth, but with some jagged spots and sharp as heck! Oh, and even with olive oil, food stuck in some places, so the pan's not worth it for the nonstick either.
