American MoMA ribbon butter knife creative kitchen cutlery Stainless Steel table knife kitchen baking cake gift

Butter has been an essential accompaniment to sliced bread for perhaps as long as sliced bread has been around. Butter is solid when refrigerated, but softens to a spreadable consistency at room temperature and melts to a thin liquid at 32 to 35 degrees Celsius (90 to 95 degrees Fahrenheit). This nifty knife is designed to prevent cold butter from turning into a lump on your sandwich, turning a hard brick of butter into a gorgeous, spreadable ribbon. Its design was perfected by a self-proclaimed "butter lover" who made many prototypes before settling on one that features a wide blade with a built-in grater to maximize coverage on sliced bread.
