Dough whisks and stainless.
Growing up I had it drilled into me that you never use anything metal (Spoons, etc.) to stir in stainless steel vessels (Pots and bowls). My mother's reasoning being that you'll scratch it all up, needless to say when I left home this was one of the rules I broke, and still have a large stainless bowl that bears the marks of my transgression.
Do Danish dough whisks scratch stainless bowls? I've only used one a couple times, but found it much more effective than a plastic spoon.
