At IKEA we want to make everyday life as simple as possible. Even when it comes to sharpening knives. IKEA 365+ GNISTRA is a knife sharpener with three ceramic sharpening wheels. By dragging the knife through the wheels in order 1, 2, 3 - the edge of the knife becomes as sharp as it was when it was new. Regardless of whether you cook all the time or only once in a while, a sharp knife is one of the most important tools in the kitchen, making cooking easier and more fun. Now it's easy for you to keep your knives sharp - 365 days a year.
