Yes, I have one too; it was my grandmother's. One time when my daughter was about 6 or 7, she decided it would be convenient to use to cut scotch tape. She was supposed to be in her room resting & reading. She got into the closet where I kept my sewing to look for scissors, found that and ended up with it going into her eye. We ended up spending the afternoon in an opthomologists office. Luckily her eye wasn't damaged, just scratched. But she won't have anything to do with the tracing wheel anymore.
