I would have assumed you'd be less likely to cut yourself with a multiblade razor as the sheer size of something like a Fusion head would make it almost impossible to dig it into your skin if you apply pressure. Those type of razors also have the blade angle built in to a certain extent so you can't get it completely wrong. Still, now that I'm used to one blade, even a double blade razor feels so rough on my skin compared to the songle blade.
