I recently got a Wicked Edge Sharpening System and want to start with the factory edge of some of my knives to sharpen them rather than re-profile all of them. The various websites of knife companies don't give the factory edges of their knives. Is there a way to determine the factory edges of knives or is eyeballing it the only way? Do I have to call each company and ask what degree edge they used for each of my knives?
