Marc,
Thanks for your very detailed and thoughtful answers. I have a few clarifying questions if you don’t mind.
For the left side lean, does this only affect full flat grinds or are you saying all knives are potentially affected? I’ve watched the videos you linked and they seem to be specific to full flat grind blades.
Also, instead of guessing the amount of adjustment to make, can’t I just put the angle cube on the sharpening stone as it’s leaning on the clamped in blade? Wouldn’t this be the angle that I’m sharpening at regardless of all other factors (such as how I’m clamped or how the knife is sitting in the vice)?
Lastly, on the knife I sharpened today (zt 0470)..even though the bevels looked kind of equal to the eye..in order to get the sharpie removed I had to set one guide rod to 20* and the other to 28*!! I was getting frustrated because I thought I had to be doing something wrong..and started doubting things like maybe I set up the system wrong or installed the base wrong. Anyways I was a bit frustrating so I’m back to studying (reading forum posts and rewatching all the instructional videos again.
Thanks again for all your help. It is much needed.
