I get what you are all saying. It's nice to see that some people here think that it is bad-ass and that it is not bad-ass. I, for one, fit into the second group. I don't think it is bad-ass... one hundred years ago this was the only way to shave and every man that did shave did it like this. And that accounts for the manliest man and the coward that runs away in when he faces the ultimate danger: a little mouse.
This makes me conclude - and that means that I think I've grasped the meaning of bad-ass... - that this is a question of perspective and history. Let me elaborate briefly.

Army vets and policemen say they couldn cope with the danger. Why is that? Because they have seen real danger in their lives. And they are also used to picture shaving as something harmless. So, the thought of having a razor - and the razor has this... aura... in popular culture - put to their faces is considered dangerous. But how come this is considered dangerous and bad-ass? Because we're involved in the aura of the razor, that tool of evil sweeney todd-ness... but we have to keep in mind the mundane character of this action: shaving! It's only shaving! How come something as mundane as this, something that wouldn't have risen any brows 100 years ago is so dangerous and bad-ass? Because we live in a safe confy world. And that puts a mundane chore in the zenith of periless actions! Shaving thus becomes bad-ass. It's not. For me, at least...

Mind me, I enjoy being called crazy for indulging in such daily danger. I enjoy watching my mother panic thinking that I'll chop my head off in no time... yes, I do think this might be a bit more dangerous than a Mach 3. But no extra chest hairs have grown on my chest... yet. And might I add that I am what most of you would consider a coward? I will avoid a fight at all times, I drive slowly, I indulge in mild sports as golf and badminton... and I shave with a straight. I am sorry, my friends. I cannot seem to find the bad-ass in shaving with a straight. Period!
