Butter Knife Magic, which is made of stainless steel, looks sort of like what might happen if a vegetable peeler and a butter knife were genetically spliced: It’s shaped like a butter knife, but along one edge, it’s got a whole bunch of tiny holes; along the other, there’s a big ol’ slice; and at the point, there’s a kind of… rounded, triangular hole. Using the edge with the series of tiny holes results in your butter basically being grated, making for easier spreading, while the edge with the big, long slice creates a single, wider butter curl. The triangular thing at the tip, meanwhile, makes a sort of cross between the two: The resulting curl isn’t as delicate as the shredding side’s curls are, but not nearly as wide as the slicing side.
