ButterUp Butter Knife

This revolutionary butter knife makes cold butter easily spreadable; it is so ingenious that it is sold at the Museum of Modern Art's Design Store—and pretty much nowhere else. A row of small droplet-shaped holes on one side of the blade function as a grater specifically designed for cold butter. Simply run the knife over cold butter to soften and gather it in thin ribbons. ButterUp has a wider blade than other butter knives, which is ideal both for collecting the grated ribbons and spreading butter more evenly. Plus, cleanup is easy since ButterUp is made from dishwasher-safe stainless steel.
