Royale Machetero
From Wookieepedia, the Star Wars wiki.
The Royale Macheteros were the elite guard of the Kashi Mer monarchy. They practiced a sword fighting style similar to Jar'Kai. Xendor was possibly one of its members.
[edit] Behind the scenes
Machetero is Spanish for "knife wielder". This could be an allusion to the skillful blade work they could acomplish or just connecting them with blades.
