Speaking from my own personal experience I can understand the frustration that this topic brings with it. For those whom the HHT is routinely attained it is a non issue. For those who never or rarely get it and who aren't getting a shave that pleases them it is a big issue.
I posted a thread a year of more ago called,"Finally Did the Parlor Trick." I had honed a razor and it passed HHT nicely and it was my first time having success with it. I found that on some razors I would get it and on some I would not. Some would get it on parts of the blade some for the length.
In spite of that I followed Lynn's advice that the shave was the test and found that even if a razor wouldn't HHT if it would pop hair from my forearm without touching the skin I would get a good shave out of it. So I usually try the HHT just for kicks but if I don't get it I am too lazy to worry about it enough to go hone some more. Now if the razor brushes my forearm hair aside it is going back to the hones 'cause I know it won't shave well.
When I was an ironworker in my younger days back in the '60s guys used to say,"If it was easy our wives would be doing it." In the '70s they had to quit saying that because our wives were doing it...... ironwork that is. :boohoo:
Well the HHT ain't easy .... at least for some of us and if your razor won't pass HHT give it a shave test and see if it passes that. If you want it to pass HHT and it won't get over to the hones and go to work. If it was easy our wives would be doing it. :)
