A tennis racquet, or racket, is used in the game of tennis to swat the ball across the court. It consists of a round frame on a short handle, with a mesh stretched across the frame. It is a period artifact: the illustration is based on an example from 1583 [Gianni Clerici, The Ultimate Tennis Book: 500 years of the sport, fig.11]. Unremarkably, the tennis racquet doesn’t seem to have been used in period armory. The handle is to base by Society default.
