Gretta Lambert's lightsaber was a prototype lightsaber created by Lexi Lambert as a test weapon that was loaned to the Force Adept Aaellu by Lexi's husband Benjamin and later handed down to Alucia Lambert in the years after her mother's death. As a teen, Alucia adopted her mother's lightsaber pike and gifted Lexi's lightsaber to her half-sister Gretta Lambert, who went on to use the weapon for most of her life.
The lightsaber utilized simple components which were contained within a durasteel hilt of a uniform design common among both the Jedi and Sith of the era. Alucia Lambert modified the weapon to include a belt hook and replaced the activation button – which had become stiff due to internal damage – before giving it to Gretta. When Gretta inherited her mother's lightsaber while on Kojiyo, she decided to retire her own weapon and placed it into storage, where it remained for the rest of Gretta's life.
