It is a 2 second repair by using your pocket screwdriver to ream the bubbler/nozzle out!

Calcium build up.

Calcium is 1.7 on the Mohs scale. Chromium oxide for comparison is 8-8.5. lead is 1.5.

My mind wanders! Calcium build up on a strop could arguably make a difference. On a hone I doubt it.

This causes me to recall that a calcium carbonate-based cleanser like Bon Ami is sometimes counseled for refreshing the surface of ceramic hones. So if it is refreshing the surface there, I suppose it is potentially capable of effecting change in other ways.

Yeah, maybe it would be interesting to try to charge a strop with calcium carbonate. Perhaps it is the one of the active/inactive ingredients in the supposedly innocuous Solingen white paste?
