Product Description Wide Range of Applications: This roller sharpener is versatile and suitable for various knives, including kitchen knives, chef's knives, and multi-purpose knives, making it an essential tool for home cooking. Easy to Use: The sharpening process is simple. Just place the blade on the roller and gently roll it back and forth to achieve a sharp edge with remarkable results. Two Sharpening Stone Angles: Two standard magnetic tilt angles ensure even pressure on the blade. 15° produces a fine edge, while 20° produces a strong edge. High-Efficiency Sharpening: We use industrial diamonds for the sharpening stone's grinding disc. One side of the disc has 400-grit coarse abrasive, and the other side has 1000-grit fine abrasive. The coarse abrasive disc easily sharpens the blade to the desired point, while the fine abrasive disc removes minor imperfections and surface roughness, providing a fine surface finish. Perfect Gift: This beautifully packaged product, served in a special gift box, is the perfect gift for friends and family, and an excellent present for any holiday or occasion.
