A fork, or any other cutlery, is usually a symbol of wealth and success. A fork, a spoon, and a knife promise a job promotion; a fork alone promises moderate but still pleasant success. A fork made from precious metals symbolizes financial well-being.
To get a cutlery set as a present indicates that someone has fallen for you and is looking for your attention.
To drop a fork and hear it clink represents good news or a pleasant event to come soon.
