UPDATE: Sure enough, the DMT slurry did not give the final edge, while the tomonagura slurry did. Touched up both & actually slightly overdid it on both--too much time on water only I think. I then tried a trick I heard So recommends for that: 5 strokes dry followed by stropping.

Haven't shave tested yet, but has anyone else tried dry strokes to fix the very beginning of overhoning on these stones?
