The unicot method says to start by performing diagonal back and forth strokes on one side only. Then switch to the other side.

Does this mean you’re supposed to do a diagonal stroke and then pull it back, as in making an edge-trailing stroke? And if you don’t flip the razor in between, how do you keep the slurry on the stone? I’ve seen a few videos and it did not look like they were doing this, but rather flipping after each half stroke. Doing that makes it easy to keep the slurry on the stone.

What am I missing?
