Fighting Claw
this was the term used by the New Republic to describe the implanted claws used by Yuuzhan Vong warriors in hand-to-hand combat. Essentially spurs of bone which are attached to specific muscles in the hands, elbow, or knees, fighting claws could be extended in a struggle with a twitch of the connected muscle, allowing the Yuuzhan Vong warrior to making vicious slashes at their opponent. The extension of the claws was a painful act, but it only served to remind the warrior of his continual need to endure pain in order to become more like his gods.
