Polymer tableware and serving pieces
Most of my tableware and serving pieces are handmade polymer handles on stainless steel blades.
The stainless steel will scratch and mark if you're not careful / leave it knocking about in a drawer. This may bother you - or it may not!
The polymer handles are very tough and will put up with a lot. However, they're not indestructible - if you overheat them they will burn or melt, if you drop them on a hard surface they may crack.
I strongly recommend hand-washing your DoodlePippin pieces, carefully drying with a tea towel and storing somewhere dry and protective.
However, if they end up in the dishwasher by accident after a raucous party when you're a bit, err, *distracted*, they should survive relatively unscathed. Just don't make a habit of it!
