Dumb question, how do you hold a single edge razor against your skin? Is there a recommended angle to use? Do you use short strokes? How long does a blade last? Thanks guys.
It depends a little bit razor your using? If it is a Gem razor, you can rest the flat "hood" of the razor against your face and drop the handle slightly from that angle. The good thing about SE shaving is you will get very good loud feedback from your SE razor, if it is cutting you will likely know it. Check out the single edge sub forum under the safety razor section to see if they talk about your razor in particular. Good Luck!

This.The head of the razor almost flat on your skin is a good starting point.
Anyone? I guess I'm just going to have to roll the dice tomorrow. If you don't hear from me again I guessed wrong. 
I open the cap, hold the blade by the sides, slide it in. Make sure that the sharp part of the blade is resting under the two little tabs and then close the cap.
I like your thinking. I need readers anyhow.I keep a large, fairly powerful magnifying glass handy. Every time I load a blade I closely examine the razor.
I check that the corners of the blade are firmly against the blade stops, the blade is held firmly in place by the cap and spring, the blade is flat against the base, and the blade gap is uniform.
This has saved my face from major bloodletting on more than one occasion.
