I just built my first saber and have always wanted a wooden one. For this first one I went as clean as I possibly could with just a hilt turned out of a solid block of red oak. The only non-wood bits showing are two brass screws that hold in the batteries on the bottom of the pommel, the switch, and the blade.

I would love to see pics of anyone else that has built a wooden saber. I need some ideas for my next one.
