I think I found the problem. Since I was re-profiling I just decided to set my sharpener to 20° on each side, assuming it was true. Problem is, the right side of my sharpener is 1.1° greater than the left side with everything being equal.
My best guess is this is a variation in my degree bar. No problem, I just moved the right side in 1° and now I am within 1/10 of a degree.
I basically took my finest stones, stuck my angle cube on the back of them, and then just laid them on the vice jaws. This is what revealed the difference. I’ll try another knife tomorrow and see if the problem goes away.
By the way, do you guys constantly re-check your angle with the cube as you progress through the stones? Or do you just set your angles one time and go about your business?
Thanks!
