If you are thinking about a knife as a gift, don’t forget to ask for a “symbolic payment” in return (a penny for example), for according to superstition, the gift of a knife will sever the bonds of friendship.

Never stir your coffee with your knife... "Stir with a knife, stir up strife".
Always hand a pocket knife back the way it was handed to you. If handed

Some believe that a knife does not belong to an individual
until it has 'bit' them, or tasted their blood. Believers in such
superstition may intentionally prick a finger on the blade of a knife
rather than risk a later, accidental cut. According to this
superstition, the knife will stay sharp longer and is less likely to
accidentally cut its owner once it has tasted his or her blood.
