In which country is it acceptable to eat a peach with knife and fork?

There's no country where it's considered acceptable to eat a peach with a knife and fork.

While some cultures might prefer using utensils for fruit in general, peaches are typically eaten by hand. It's generally considered more practical and less messy to simply bite into a peach.
