The Blades of Hexacting Separation, also known as the Predator Blades, are a Relic used in the Hunt game mode. The host of a world must have collected the predator blades, Optic Camouflage and Thermal Vision Helmet to play the Hunt. The Predator Blades are used by the Hunter to attack the Hunted.
Due to The Hunt requiring the Hunter to have Optical Camouflage active, the blades are only visible with a texture when collecting the Relic.
The Blades of Hexacting Separation Relic was released into the game in Content Patch 1.09 on August 10, 2011.
