I have run into my fingers--no damage. I dropped the cutter on my bare foot--no damage. I tend to use dull blades. Too cheap to change them often. I'm like klc I do more damage with pins and needles. I'm always sewing my finger into the project. I also have a spot on my middle finger that the needle always finds. It doesn't bleed, just hurts with every stitch and I have a lot of trouble with a thimble. Poor Me!!
