I did that the very first time I shaved my legs - in 7th grade. What a mess. Blood kept running down my legs off and on all day (why wouldn't it w/ 35 gashes - and I have blood that doesn't really clot very well). Of course I went to Catholic School - the nurse was a Nun, Sister Andre, and boy was she mad. So was my father when he found out I dulled his razor. After that I used the disposable kind. I still have a couple of scars from it.
