Who knows why the old man said he couldn't take other people's scissors and kitchen knives? Said it was bad for the person who took it, thank you.

In some places, it is a custom that pregnant women "can't take other people's scissors and kitchen knives", saying that it affects the development of the fetus is actually superstition. But I haven't heard that ordinary people "can't take other people's scissors and kitchen knives" and "say it's bad for people who take them". The old man is over 7 years old and has never heard of it.
