Well I took the giant leap and bought a set of swiss diamond fry pans, and two small sauce pans. Sofar I LOVE them. Nothing sticks, they cook even, they don't warp like most of the cheap supermarket ones we've bought in the past, and I expect them to last a LONG time. You can see the difference when simply boiling water, rather than seeing the pattern on the bottom of the pan when the water starts to boil like our cheap pans, the water boils around the whole pot, even up the sides. We also cook with less heat! Can you scratch them? I feel if you dug a fork into it you could, but we don't plan to. I plan on getting some of the larger sauce pans, and maybe a stock pot. I'm loving these pans!
