The 15° angle is designed for precision, producing a finer, sharper edge that’s best for Damascus and high-quality carbon steel knives—perfect for delicate, detailed cuts.

RollSharp© Magnetic Knife Sharpener delivers a powerful balance of simplicity, precision, and professional-grade sharpness—outperforming traditional sharpening tools and services.
Compared to a Honing Rod
Honing rods help maintain an edge by realigning the blade, but they don’t actually sharpen it. RollSharp© uses a diamond-coated sharpening surface to perform true sharpening, restoring dull knives to like-new sharpness.
Compared to Pull-Through Sharpeners
Pull-through sharpeners may be fast, but they often remove excessive material, shortening blade lifespan. RollSharp© features a smooth rolling action and magnetic angle control, ensuring consistent sharpening without unnecessary wear.
Compared to Whetstones
Whetstones can produce excellent results, but they require time, practice, and precise technique. RollSharp© delivers whetstone-level precision with preset angles, making professional results achievable in minutes—even for beginners.
Compared to Professional Sharpening Services
Professional services can be effective, but they cost time and money, and you’re without your knives while they’re serviced. RollSharp© lets you achieve comparable, pro-level sharpness at home whenever you need it—no waiting, no hassle.
