I started shaving - face grooming - with a straight razor. I do not think I will shave my privates again ... unless I am looking for a position on the Vienna Boys Choir.
When someone says razor sharp it does not mean "box cutter sharp"; it really means the sharpest thing in the planet. I can hold a hair from my head between my thumb and index and cut it in half with on stroke!
