Based on the traditional skills of swordsmanship, the modern sport arose at the end of the 19th century, with the Italian school having modified the historical European martial art of classical fencing, and the French school having later refined the Italian system. There are three forms of modern fencing, each using a different style of weapon and different rules, and as such the sport is divided into three competitive scenes: Foil, Epee, and Sabre. Most competitive fencers choose to specialise in only one weapon. - Erinn Smart (born January 12, 1980) is an American fencer who was a member of the United States Fencing Team at the 2008 Summer Olympics in Beijing, where she competed in the women's individual and team foil events.
