This knife sharpening tool is equipped with a 400-grit diamond surface on one end, specifically designed for precision sharpening of knives; the other end features a smooth ceramic surface for polishing the blade, restoring the knife to a like-new condition. Its unique multi-angle base offers four sharpening angles of 12°, 15°, 20°, and 25°, fully meeting your diverse needs. The 12° and 15° angles are tailored for knives that require extreme sharpness, such as sushi knives and high-carbon steel knives, ensuring a silky-smooth cutting experience. Meanwhile, the 20° and 25° angles are suitable for knives that need more robust edges, effortlessly handling heavy-duty kitchen cutting tasks and giving you confidence with every stroke. Compared to traditional sharpening stones, our rolling sharpener provides a more effortless and convenient operation, seamlessly blending practical functionality with refined craftsmanship to deliver an unparalleled sharpening experience. We use premium gift box packaging, making it an ideal choice for both personal use and as a gift for friends and family. Whether you're a professional chef, a knife collector, or an outdoor adventure enthusiast, this sharpener will be an indispensable assistant in your kitchen or backpack.
