I asked him to try this:

Create a slurry on the coticule
Honing on it
Every once and a while keep the slurry wet, but not diluted.
When you feel the slurry stop cutting, dip your slurry stone into water and refresh more slurry on the old slurry
The edge will start to cut more and more.

Repeat this 5 or 6 times

Finish with a slurry but make sure it is wet,.

Test shave.


my theory is that the garnets don't "Break down" per say because they are very hard, but I think when they bang into each other during honing, their edges dull, causing the edge to be gentle but sorta dull as if their cutting ability diminishes, sometimes the edge is not quite there. By refreshing you can keep the garnets sharp.
