Reptilian blade
A Reptilian blade was a type of knife used by the Xindi-Reptilians in the 22nd century. It had a serrated cutting edge.

In 2154, a knife of this configuration was used by Xindi-Reptilian Commander Dolim when he murdered Xindi-Humanoid Council representative Degra on the Xindi Council planet. In Degra's final moments alive, Dolim vowed to him, "Your traitorous bloodline will end at the tip of my blade." ()
