Do plastic utensils with metal handles or metal on handles need to be toiveled?

If it is a metal handle with plastic utensil, then you do not need to tovel. But if it is metal with plastic or rubber covering the metal (ex. infant feeding spoons), then you do need to tovel

Do I need to be crazy careful that the food doesn’t touch the metal handle ?

You do not

Thank you
Why isn’t it considered a yad that requires tevilah

If it’s a metal pot with Metal handle, you need to dip the whole put including the handle
