I faced issues with a narrow chisel recently. Part of the problem I found is the rounding of the bezel from left to right.
If you apply pressure to one side the chisels edge deviates from the angle: one corner lower than the other. I try compensating for this by putting pressure on the other side to even it out. What wound up happening is the other side of the chisel gets ground down and the previously lower edge is higher now. I would reverse the process and eventually figured out that the center of the bevel is higher than both corners. I realized that the chisel started to form a belly in the middle part of the bevel (if you hold the chisel at the sharpening angle it now rocks left to right ever so slightly). The solution for me was on a coarse stone focusing on straightening the bevel surface going a couple of strokes at a time and each time wiping the blade and checking the burr and looking at where Iām bringing down the bevel. Eventually going real slow a few strikes at a time, and lighter pressure, I was able to get the edge straightened out. At this point I was able to rely on the flatness of the bevel to sharpen, and move to finer grit. This took about an hour to realize and straighten. -
