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

In some places, there is a custom that pregnant women "can't take other people's scissors and kitchen knives", saying that it is superstitious to affect fetal development. But I have never heard that ordinary people "can't take other people's scissors and kitchen knives" and "say that people who take them are not good". The old man is over 70 years old and has never heard of it.
