I'm also of the school of thought that a significant change in the size of the razor may be to blame. For example, I rarely if ever nick myself. Well, about a week ago I grabbed a very small 4/8 razor and nicked myself 2 + times! In all fairness it may have been in need of a stropping or maybe even a honing. I really couldn't remember if it needed either. So I just put it on my desk to make sure it gets both before I put it away again. Of course, it's still sitting there.
