Well, yesterday was the Sunday shave, and I may have found the nicest touchup ever.
First, raise the lightest slurry on the BBW with two or three swipes of the slurry stone. It should look mostly like water, or what your slurry looks like by the end of the Dilucot procedure.
Then two sets of 15 half-strokes, the second one diluted by a fingerload of water. After that some X-strokes on the Coticule side with water. I did 2 x 30. Linen, strop, shave.
Like a hot knife through butter.
