Cold butter is no match for EAtoCo’s two-sided stainless steel knife. Slide the edge that’s finished with tiny loops along a stick of butter and you’ll get long, thin ribbons that melt instantly on a piece of hot toast—even if your butter came straight from the fridge. (The same edge works great on soft butter, too; those curlicue ribbons spread across soft, delicate bread without tearing it up.) Flip the knife over and you have a serrated edge that’s sharp enough to cut through English muffins, toast and even fruit, making this the ultimate breakfast tool. Plus, you can use the serrations to scrape any unwanted burnt bits off your toast without sacrificing the bread underneath. One final design perk: The Nulu knife’s blade is angled upwards from the handle, which means you can rest it flat on your table without smearing butter everywhere. EAtoCo’s tools are handcrafted by highly-skilled craftsmen in Japan’s Tsubamesanjo District of the Niigata Prefecture—the country’s center for hardware production.
