I also wanted to add the (although controversial and highly subjective) I've tried the HHT on my blade. As I've said, I have some thick hair and used my own head hair, so from what I've read about the test, it didn't really surprise me that my blade failed, but what did surprise me is that the blade didn't even grab onto the hair at all. I even tried to move the hair in a cutting motion across the blade and it just bend by the blade with no grab at all. Any thoughts?

Along with the HHT, I tested the blade on my arm hair (back of the hand/wrist to be more specific) and it seemed to shave at the base just fine, but wouldn't cut the hairs at the tips (I've read that this is a pretty good test to determine shave readiness).
