Yep, it happened to me, although it was totally my fault. I had been given some dies for the Studio, and I slipped my hand between them and lifted up the one on top, not realizing about the blades, and the weight of the die caused the blade to slice right into the back of my hand. I almost needed stitches. It put me off the whole device for awhile, but I finally got back in the saddle, although I am a whole lot more careful now.
