The Echani foil represented a sword made as a tribute to Raskta Fenni, who was considered the most skilled Echani duelist of her era. Although numerous copies of these weapons were made and sold, the complex cortosis weave that made them resistant to lightsaber strikes meant that only a small number endured.
In approximately 3956 BBY, Commander Grann, a Sith emissary located on the planet Manaan, possessed an Echani Foil.
