I too have cut myself with the rotary cutter. i ended up wtih four stitches. I guess i was cutting too fast cause the blade jumped the ruler. Every time i use that ruler now i see the mark in it and remember to slow down and keep my hands out of the way. But my husband got me a set of suction grips from Harbor Freight and now i only use them when cutting. I love them and keeps my hands out of the way.
