F's lightsaber was a lightsaber wielded by F, a Jedi Padawan, at some point following Order 66. Its blade was yellow and tapered to a point. Upon activation, the three-part guard split apart horizontally, creating a ring of plasma that matched the blade's color. The hilt displayed a blue element on its right side, positioned vertically beneath a red circular element close to the top. Additional blue elements were visible on the left side. The red element was present on both sides of the hilt.
