Rass
the bones of this predator, native to the planet Saki, were used by Sakiyan hunters to create handles for knives other bladed weapons. The black surface of a rass bone was pebbled and hard, providing a grip that wouldn't slide around in a bloody or sweaty hand. The use of a rass-bone blade indicated a hunter's prowess, since it indicated that the wielder had taken down one of the most vicious predators on their homeworld.
