We're on the same page, Russel. The idea may sprout that I over emphasize on the HHT, but I ''m really only considering it for the sake of the experiment.
The premise is this: If striations offer a substantial advantage with cutting hair, than the HHT should reflect that. The success of that test should peak with striations, dissipate when the striations are evened out, and improve again when the edge becomes so sharp that striations don't matter any more. So I would expect a fine HHT at 1200 grit level (approximately), so-so results around 6000-8000 grit level, and peak again at 12000 and above.

Of course one can't do pyramids on this experiment, and I refrain form using the coticule, because I have strong suspicions that other principles are going on at the same time with the use of coticules.

Are you saying, that with a progression on DMT-hones, you didn't find any evidence to sustain the above premise?

Thanks,

Bart.
