Thanks for all the replies so far, gentlemen.

It seems this has boiled down a bit to a discussion about the HHT, which was not really my intention. My original goal for starting this thread is to find out if and where striations, or thoothiness -if you wish- come into play when sharpening a razor. The HHT tests how well an edge severs a hair, which seems at least of some relevance to me, but for this experiment that all does not matter.
If a person progresses trough a series of grits, and he performs the HHT at each grit level, then it's safe to suppose he 'd do so in the same fashion, with the same hair, on the same razor. The only variable would be the grit size of the hone. IF THE HHT JUST KEEPS IMPROVING TILL IT MAXES OUT, THEN THAT MEANS "TOOTHINESS" IS NOT AFFECTING THE WAY HAIR SHAFTS ARE PENETRATED BY AN EDGE.
IF, HOWEVER, THE HHT DISSIPATES, AFTER A CERTAIN GRIT LEVEL, TO IMPROVE AGAIN AT A MUCH HIGHER GRIT LEVEL, THEN THAT MEANS THAT TWO DIFFERENT TYPES OF EDGES ARE CAPABLE OF POSSIBLE SHAVE-WORTHINESS.
It would be a starting point for further investigation.
Like I said, I have no means to do this experiment myself. I understand that Shaptons all have the same type of abrasive medium, so I really think that would be the hones to perform such experiment. Doing it on different types of hones would be ambiguous, because of the difference in abrasive media. So I humbly beg to you Shapton owners out there, to perform such a progression, perform a HHT at each level, and report your findings in this thread. I would be most grateful.

Thanks,

Bart.
