Abstract
A special effects device for providing an energy sword effect. The device includes two long plastic semi-cylinders, and these two blade body members are rolled perpendicular to their length, which creates compact cylinders of material of small volume that can be provided on a pair of spools in a hilt. To extend the blade, a motor provided in the hilt unrolls the blade body members from the spools. Each blade body member passes through a blade forming guideway that nests the semi-cylindrical blade body members together as they leave the hilt. To retract the blade, the process is reversed. The lighting of the blade is achieved with a flexible strip of light sources. The light source strip is attached to a blade end cap and positioned in the center of the two blade body members such that it is pulled up along with the blade body members during their extension.
