I started out shaving (like most, I imagine) with a variety of electric razors. They can give you a so-so shave fairly quickly, but take a while if you want to get a close one. And since most of them need to be used dry, they're fairly limited.
Eventually I moved on to using disposables, although I think I use them a little differently than most. I will use them for quite a long while; mostly, you just need to make sure to wash them every time you use them. I started this when I found out that most razors are ruined by corrosion, not by dulling. And this works pretty well; use them in the shower, wash them, and blow them dry. It isn't really fast, but does give a very close shave with nicks and cuts being very rare.
But I've long been intrigued by the possibility of going to a real razor (I was even thinking about a straight blade). After doing some reading, a double-edged safety razor seemed a better choice. So I finally broke down and bought one a few days ago. I tried it out today, and was pretty happy. I actually used it about the same way I normally use my disposables, and it worked out just fine.
I surprised myself by not getting any cuts or abrasions, and it was a bit quicker than my normal. I think it didn't end up being as close a shave, although I mostly attribute that to being in a bit of a hurry. I suspect it will end up being pretty similar in both time and closeness, although most would argue that I'm still not doing it right.
That is, I'm not using a brush and foam to really set up the hair, and using them after the shower. Perhaps an experiment for another time.
