But you need to really get lucky. I've shaved with this a few times. Its something that takes extra concentration to keep the angle proper and not slice your face open! As the angle is very hard to see. you have to watch the angle of the scales when shaving as the angle of the blade is had to see.
BTW, This is a 2/8 razor.
