Cross grinding is a technique used in the sharpening of blades or tools to ensure a more precise and uniform edge. By grinding the blade in a crosshatch pattern, it helps to remove any burrs or imperfections left from previous sharpening methods. This results in a sharper edge that is more durable and consistent, making it ideal for tasks that require precision and control. Overall, cross grinding helps to improve the performance and longevity of the blade or tool. **
