Keysaber

A Keysaber is a weapon similar to a sword. It projects a laser beam that forms into a key shape. The typical Keysaber hilt consisted of a metal cylinder between twenty-five and thirty-five centimeters in length. However, the size of individuals hilts varied drastically, as the weapon was tailored to the creator's specific needs and preferences.

Description
Due to the weightlessness of the laser and the strong gyroscopic effect generated by it, Keysabers required a great deal of strength to wield, and was extremely difficult—and dangerous—for the untrained to attempt using.
