kurtismj,
As others have said do not worry about the HHT !
As I have have a 'high & tight' haircut, the only suitable hair I have in the house is my wifes.
Her hair is so fine that no DE razor blade, not even Feathers, will pass the HHT with it. What does that prove ? - absolutely nothing ! :)
Just shave with your razor; as Mr Abrams has said, the shave will tell you everything you need to know about your razors edge :)
Have fun & good shaving !
Best regards
Russ
