The first few months I used a straight it seemed there were about 3 or 4 places where if I was going to cut myself those were always the same places. I would guess it was a matter of playing with technique in those areas and giving them extra concentration and they ceased to be a problem. The worst cut I ever got shaving was during the second week when I thought I had this all down pat. It was at the right side of my mouth just below my lower lip. I was doing a WTG stroke and actually watched my hand do a sideways movement I didn't want it to do like it was possessed or something. I didn't need any stitches but it was one deep cut which left a nice scar which always reminds me to this day to think first and move second.
