This lightsaber hangs at the ready on the belt of Jedi Knight Ki-Adi-Mundi.
Like most of the lightsabers, this one is constructed of a resin casting of a custom machined shaft, painted silver and assembled onto a 3/8" diameter steel rod. Each end of the prop was finished with metal found objects.
The lightsaber's blade emitter was probably made from a radial bearing retention or retainer ring, used around the collar of bike handlebars. An exact matching bearing has not yet been found. This piece is used again two more times below the short metal cylinder under the emitter. A fender washer (1 1/2" diameter) was inset in the top ring.
Further down, at the thinnest part of the lightsaber two rubber O-rings were used.
A red LED light bar was mounted on the prop's side. Other small parts used for the lightsaber's controls include a 5 mm LED with a chrome metal bezel (1 cm diameter), a brass thumbscrew and a silver knob.

On the very end of the prop is a metal cap. This same part is used on the diagnostic screens used by Shmi and Anakin Skywalker.
The round black piece on the handle is half of a system for attaching the saber to the Jedi's belt. The other half is a clip worn on the belt that the "knob" on the prop slides into with a simple downward action. By design, the prop remains free to pivot within the clip and is released simply by pressing the two arms on either side of the clip.
