Have there been rule changes in fencing?

Answer 1

Yes, there have been many. For example, before the introduction of the electric scoring machine, there was only 'dry' Fencing. There were multiple directors to ensure that no touches would be missed, and the 'honor system' was used. However, it was soon proved much more beneficial to use an electric system, where the blades are connected to bodycords, which are subsequently connected to the lame's(in Sabre and foil), and also connected to a reel, which registers touches on a scoring machine. With this machine, fencers had to adapt to different timing in attacks, as well as the 500milligram minimum weight required for the scoring light to go off.

A recent example of a rather significant rule change is that foilists are now required to wear electric bibs. The bibs on a foil mask are thought to be covering target area, and are now being electrified. This rule will take effect starting in the 2009 Senior world cup.

Are there any specific rule changes you're looking for?
