For really screwed up knives or to change or make your own angle these stones make the task very easy.
Pretty good mirror edge achieved! I can go a little bit further if the need or desire should arise.
This tool will allow you to identify the parts of the sharpener you currently own, and then guide you to the upgrade kits that are compatible with your sharpener. In each step, select the part that matches your current hardware. To select the part, simply click on the image. There will be multiple steps in the process.
NOTE: The Wicked Edge GO WE50 and the Wicked Edge GO WE60 are not compatible with any upgrades at this time.
