In fencing, what gives left-handers the edge? Views from the present and the distant past.

Recent studies show that in the sport of fencing left-handers have an advantage over right-handers. This was recognised by fencing masters as early as the sixteenth century. They also agreed that the advantage was due to left-handers' numbers-that being a minority gave them more opportunities to compete against right-handers than right-handers had against them. Fencing masters today have reached the same conclusion, as have laterality researchers, who see the advantage as an example of what is now called a "frequency-dependent" effect. However, some researchers have also suggested other possibilities that relate the advantage to natural differences in ability. This article presents a sampling of views of fencing masters from the past, along with a summary and analysis of explanations, old and new.
