Lightsaber 'spoke' seting

"Luke removed the lightsaber from his waist, very slowly adjusted the controls set in the handle.
...Luke activated his saber. Instead of the meter-plus shaft of white energy, the pommel put forth a short, needle-thin spoke. With concentration worthy of a master craftsman, Luke stepped forward and moved the energy beam along the slight space visible between door and frame. A third of the way down the door a distinct click sounded and the door slid obediently aside. Readjusting his saber, Like flicked it off and replaced it at his waist."
 - From Splinter of the Mind's Eye by Alan Dean Foster

The spoke can be very precisely used for:

Cutting or Attacking
 - The 'spoke' can cause 1d6 damage to material or a Being.

Repairing
 - Using the 'spoke' while repairing equipment lets you add 1d6 to a Repair roll.

Disable Device
 - The 'spoke' adds 1d6 to a Disable Device roll.

The setting gives off a slight energy disruption effect, detectable by sensors.

It takes a Move action to activate or deactivate the setting.
