Thanks for the help, appreciate it. So a question, regardless what angle I am starting with (staying with this one just to keep it easy though), if I start at 26.85 dps, starting with 800 say, then go to 1000 and check the edge angle and reset 26.85, won’t the angle be slightly different than what I finished with from the 800? I’m thinking even if I only take off a tiny bit to make sure I am getting a burr on both sides, isn’t the angle going to slightly increase, and then when I go back to 26.85 I won’t be getting to the edge?
I think you’re conceptualizing the sharpening process incorrectly. If you set the angle to 26.85 degrees (or any other angle) it will stay at that angle unless you change stones or change the setting. You can prove this to yourself using a sharpie to mark the bevels and a magnifying device. Once you change grit levels, check that the new grit is also reading exactly 26.85 degrees. Then mark the edge with the sharpie and do a few light passes with the stone. If you look at the bevels with your magnifier you should see that the sharpie was removed evenly all the way to the apex of the bevels. If the angle had become more obtuse like you’re concerned about then you would see that the sharpie would remain at the very edge of the apex.
While you certainly can create a burr at each grit in the process to ensure that you’re always reaching the apex, this is unnecessary. It will become increasingly difficult to detect the burr as you move into the finer grit levels.
