When I was younger, I always liked playing around with flashlights. It was fun pretending they were lightsabers as I wooshed and zoomed around my house. However, flashlights hardly look like any Jedi or Sith's lightsaber. 

In addition, most flashlights feature incredibly unwieldy grips. Although most affordable flashlights nowadays sport some kind of rubber grip, the flashlights I used as a kid were literally a solid tube of plastic with a switch. 

Creating an ergonomic flashlight handle that resembled a lightsaber seemed like an excellent redesign for this project.
