Well I'm not shaving my head, so perhaps so
Anything else I can think of is X rated.
I've used diamond pastes in the past on ceramics with good results, but using the diamond films on ceramics - Good move, Tom!
I do have youtube videos of the diamond films on abrasion resistant steels - CPM-M4 for instance. They really go through the steel pretty effortlessly. And going past the films to 0.025 poly - I can't wait to see the microscope pics!
In the past I've sharpened and repaired ceramic knives, starting with diamond plates. In particular for more drastic repairs using coarse diamonds, you do run the risk of chipping out an edge, so be careful with XXC plates or 125 micron and 165 micron films. It may be necessary as, even with diamonds, it can be a bit of a slog. I did a repair where someone had tried sharpening the knife and he did succeed in giving me an extremely dull and chipped ceramic blade with a broken tip.
Now, when I really need to do some serious repairs, then I go to using my diamond BELTS! A 2x72" 125 micron belt on a variable speed grinder is a real weapon for ceramics and abrasion resistant steels
Tom's choice of starting with a 75 micron film is ... a PERFECT choice!
