Ouch! I haven't cut myself.....yet...... with the cutter while cutting fabric, but I have cut myself by forgetting to close the rotary cutter blade guard, then somehow brushing my hand against it while it was laying on my cutting mat. Now I use the older Olfa cutter that you have to squeeze the handle to make the blade come out so you can use it. (The cut wasn't bad, but it taught me a lesson!)
