Many thousands of years ago when I was weeeeeeee lad, my mom was sewing on the kitchen table. She was using a black machine of some kind. At some point she sewed her finger into her work in such a way she couldn't get the set screw out. I had to do that. Not fun for a weeeeeee lad to have to do. Mom then proceeded to pull the needle out, bandage the finger and continue with her sewing.
Lesson learned. Joey don't get no digits near that sharp poky staby thing. Nuh uh.
