Re the pic above, I was using the open flat screwdriver blade, with my thumb resting where the arrow is pointing, to grip the handle, Right there is the corner of the (very sharp) chisel blade. Without doing anything apparently unsafe, even closed, it slashed the tip of my thumb deeply. I did not need stitches but it took a couple of hours to stop bleeding and a week to heal.
Be careful out there!
