Palette knives are used for smoothing, lifting or spreading creams, sauces and other culinary creations. Their purpose is similar to that of a spatula except that it features a blunt, rounded end.
When used for cooking, a palette knife is sometimes called a "frosting spatula." It is not used to cut cakes or other pastries because it does not possess a sharp edge. Instead, it is used to gently spread or apply soft materials. Although its most common applications involve pastries and desserts, it is also useful for spreading condiments on sandwiches and other similar applications. It can also be used for creative design in terms of sauces and frosting.
