A pair of ulaks.

" The ulaks had first been forged by the ancient monks, used in defense of honor."
Riddick musing about ulaks on Aguerra Prime. [1].

Ulaks are curved single-edged knives with serrated edges typically used in tandem.


These "swingblades" are capable of slicing and stabbing positions, and are designed to compliment the natural motions of a person's arms and hands in close combat. The serrated edge is used for blocking other bladed weapons.


Richard B. Riddick took a pair of these from a mercenary on-board the Dark Athena. Several years later he acquired another pair from a guard at the Crematoria Slam Facility.


The props used for the ulaks in The Chronicles of Riddick were blades purchased from Axtion Bladez Concepts with customized handles. [2]
