I've been really fighting to get my razors to pass the HHT of of the hones. I have had very little success in doing so the last few month. so today, just for grins i plucked a hair and grabbed a new DE blade (generic) to see if the DE blade passed it with my hair. Alas it did not. So either straights are supposed to be a lot sharper than new cheap DE blades, or some of my hairs are to fine to use as a guage.
