I always aim for a positive HHT after my DMT 1200. It takes ultralight strokes to get there. I keep a little box, filled with freshly washed, thick hair that I "harvested" from my youngest daughter's head. (She's pride to be part of my honing activities, something she monitors with utmost attention). My own hair works too, and so does my wife's and all other hairs I tried, but my daughter's is the easiest to cut.
I have further standardized my version of the HHT, by pinching the hair between my moistened thumb and index finger and dragging it through. Then I let it settle for a few seconds, so that the hair is well hydrated. It makes a difference.

After the DMT I sometimes, but not always loose the HHT ability while honing on the Belgian blue and the coticule. After stropping a freshly honed razor on leather, my razors must pass the HHT, or I don't even bother with trying to shave anymore. (never had a decent close shave after ignoring that rule). At this stage, a truly sharp razor will fell a hair the split second it touches the edge. At the DMT 1200 stage, I accept that I need to drag the hair accross the razor for 1mm or so, before it catches the edge.

Best regards,
Bart.
