In William Golding's "Lord of the Flies," Jack Merridew uses various weapons throughout the story, primarily as symbols of power and savagery. Initially, he starts with a knife, which he uses during a hunting expedition. As the story progresses, he becomes more focused on the hunt and the control it affords him.
Later, Jack’s group creates spears for hunting, and he also employs fear and intimidation as psychological weapons to dominate the other boys. Eventually, as his descent into savagery deepens, he uses a more violent and aggressive approach to leadership, culminating in a turning point where he wields a spear and uses it in a violent confrontation. The weapons Jack chooses signify the shift from civilized behavior to primal instincts and highlight the overarching themes of savagery and the loss of innocence in the novel.
