Why can't broken pots and bowls be used?

Since it's a broken pot and bowl, it can't be used any more. First, it's easy to hurt your hand, because the edges of the broken pots and bowls are sharp, and it's easy to cut your hand if you are not careful. On the other hand, we have no place to repair the pot now. Unlike the broken pot in the past, we can repair it and reuse it. If it is broken now, it will leak below and it will definitely be useless.
