Yes, after many years of using a rotary cutter, I finally dut a chunk out of my middle finger Don't ask me how I missed my index finger and hit the middle, but it really bleed. I live too far from ER and so I just taped it up, and went back to cutting, being a whole lot more careful now. I really need to invest in a better cutter. Like one that has a sensor when it leaves material and goes airborne toward human skin. Do they make such a thing? lol
