My Christmas present to myself. At least, that's my story and I'm sticking to it.
The hilt, custom built by Parks Sabers, is a replica of the Star Wars Expanded Universe character of Quinlan Vos. The blade is detachable, and is made from polycarbonate, which makes it really hard to break (and hence suitable for duelling). There are LEDs inside the blade so it has that neat extension/retraction lighting effect.
Unlike the Force FX sabers, the Parks Sabers sadly don't have sound, but that actually makes the hilt sleeker, less bulky without all those extra electronics, and probably easier to wield and twirl.
Next up, to get some Jedi robes together and start brushing up on some lightsaber combat forms...
