...I have a theory. Help me with this. My theory is the hanging hair is cut when there are microscopic "teeth" or a very sharp but rough surface on a blade (something to "grab" it), but will not be cut when there is a sharp but smooth surface. And that is why you can still get a good shave even though a razor does not pass the HHT. Am I right on this or full of sh8# ? Thanks for your comments.
