Fencing was an ancient Earth sport where two competitors in protective clothing faced off against each other armed with thin, blunted sword-like weapons. Each of three different weapons (foil, saber, or épée) had different rules. For example, saber was the only weapon where one could use their sword in a cutting motion. The aim of the sport was to score points by making "touches" with the weapon on the opponent's body. The winner was the one who first reached a certain number of points.
East Syracuse Kennedy Middle School was famous for its middle school fencing program, and the University of North Carolina at Chapel Hill committed Ariane Binks for fencing while the latter still was in middle school. (Star Trek: False Vacuum: "Black Tornado")
