The kal'hris can be used in many ways, either as a slicing axe, to jab using the spike on top, or alternately to help climb ice cliffs. Having so many edges on the weapon, it allows the user to attack with unusual angles.
Their design is loosely defined and can be almost any size (some being so long they are "technically pole arms.") The handle generally ranges from 75-180 cm, the blade 15-28 cm, and the spike 10-25 cm. They typically weigh between 1.8 and 4.9 kg. Many Andorians like to elaborately decorate their kal'hris, hence the translation. (Last Unicorn RPG module: The Andorians: Among the Clans)
