Warning: Pay attention to what you are doing!
I just finished my 21st SR shave, which I must say was my very 1st BBS with my father's 5/8 King Mfg. Co. However, I was switching hands from right to left and must have not been paying attention to what I was doing. Some how I touched the edge with my left thumb pad and it sliced it pretty bad. Not bad enough for stitches, but I thought it would never stop bleeding.
So just as a warning to beginners, please be cautious of what you are doing and pay attention. It is very easy to do serious damage with a SR and it only takes a micro-second.
