I had a slightly different problem honing. I started on the 1k to get a deep chip out so I probably used about 100 light laps switching between the x pattern and just a straight perpendicular stroke. When I was done the chp was gone but the edge was concave. To give an idea I removed about a 1/16th inch of metal in the middle and almost none at the heel and toe. I flattened my 1k 3 times and attempted to fix the blade but it just got worse. Only thing I can think of is maybe the stone itself is convex but since I flattened I'm not sure. It's a dovo 6/8 with hollow gring and rounded tip and I used the tape method. Any Idea what I'm doing wrong and how to fix the blade?
