My stubble is itching a bit tonight and it got me to thinking.
Showing my age I started shaving with one of those razors that opened and you dropped in a blade that had two edges, one on each side. I then went to disposables with one blade then two blades. "The first starts cutting and pulls the whisker up and the second cuts it below the skin line" at least if you believe the commercials.
Then 3 blades!
Then 4 blades!!
Then 5 blades!?!?
