Almas Sword is the sword Alma used while fighting Amlici. Alma “fought with Amlici with the sword, face to face,” and the two men “did contend mightily, one with another” (Alma 2:29).
After Alma spoke, he contended again with Amlici. Alma “was strengthened, insomuch that he slew Amlici with the sword” (Alma 2:31).
