Whisks are made from loops of fine wire joined at the handle. There are a number of different sizes and shapes of whisks used for different tasks. Large balloon whisks, for example, are best to incorporate air as when whipping cream.
The French or Wire Whisk is made with stiffer wire and a more elongated shape. It is used to blend ingredients until smooth as in pancake batter.
You may find in many recipes that ‘whisk’ is often used interchangeably with the term ‘whip’.
