I think you're looking too hard for a material issue. Plastic kitchen utensils can last just long as metal. Really. I have several plastic strainers from the 80s that are still in use, and several plastic handled knives from 2000s that feel great in my hand. I've also thrown away metal ice cream scoops (yes from Amazon) months after purchase because they became pitted with rust. (And nobody want's rusty ice cream!) The hidden problem is our throw-away economy. Things are just designed to fail now, because everyone want us to simply keep buying.
