Some bad info in that old article:

(2) Check the blade's cutting edge for nicks. Don't accept even the slightest imperfection and don't let the man tell you that such nicks will come out. It's your face, baby, and a jagged cutting edge will make it look like a battle map, and no, those nicks won't come out.

Lots of us have honed out microchipping in blades...they DO come out and it's hard to believe that they didn't have knowledge to do the same fourty years ago.

(3)Plain or fancy, its primary job is to give you something to hold the razor by

holding your blade by the handle is asking for trouble...

(1) Always shave against the grain. That is, if your whiskers grow down, shave up. Shave cowlicks twice, once up and once down. When you make razor strokes only with the grain of your beard, you're not shaving, you're just scraping your face and it'll feel like it.

You've got to be a true he-man to only do a single ATG pass...think I'll pass on that bit of advice.
