A butter knife is a kitchen utensil designed primarily for spreading butter, margarine, or other soft spreads. It typically has a blunt edge, which makes it safe to use and prevents cutting into bread or other foods. Butter knives are often made from stainless steel, plastic, or wood, and they come in various shapes and sizes. These knives are commonly found in households and restaurants, often included in place settings alongside forks and spoons. While their main purpose is for spreading, they can also be used for other soft foods like cream cheese or jam. Kitchen utensils and tableware often include butter knives as essential items.
