This can be achieved by positioning the blade against the grinding wheel at the correct angle and applying even pressure as you move the blade back and forth. Remember to take frequent breaks and dip the shears in water to prevent overheating.
In conclusion, sharpening hedge shears with a bench grinder is indeed possible and can be a convenient way to restore their sharpness. However, it is important to use the correct grinding wheel and maintain the proper angle to achieve the desired results. By following these guidelines and taking precautions to prevent overheating, you can effectively sharpen your hedge shears and keep them in optimal working condition.
