I was watching Lynns DVD, and in the honing section he said that a way to tell if his razor has been sufficiently honed was to hold a hair in mid air and slice it in half with the razor.

Having just tried this with razor I found that it's not sharp enough.

I have used my razor 8 times with 2 passes each time.

My question is: At this point should my razor still be capable of slicing the hair in two?
