Long knife
From Wookieepedia, the Star Wars wiki.
A Long knife was a type of weapon used by Chay Praysh's Drach'nam guards in his palace. The long knives were in essence a long version of a knife, shorter than a sword, and used almost exclusively as a close-quarters melee weapon. These knives sported a hilt with spikes on it. They did not have vibroblades, and were ineffective against lightsabers. They were carried with a neuronic whip.
