Abstract
Abstract A sport fencing device comprises an oblong striking element made from a foam material, a handle attached to the striking element, and a stabilizing element interconnecting the handle with the striking element. The sport fencing device further includes a contact detector, for example, a pressure sensitive switch located in the forward end of the striking element. When the forward end of the striking element makes contact with an opponent's body, the switch is closed and a point is scored.
