My mother used to say that giving a knife as a gift was bad luck unless the recipient "bought" the knife from the giver with a small coin. If you didn't do this, the knife would cut off the relationship between the two people in some way. This was especially important when giving a kitchen knife set as a wedding gift. Do you believe giving a knife as a gift is bad luck? What other gift or wedding superstitions do you follow?
