Elias pressed it gently into the boy's hand. "It reminds you that 'I' is not a noun," he said. "It's a verb. You don't have a self. You tool one, every moment, with every choice."
Elias chuckled. "Good. That means you're about to begin."
Years passed. Elias grew old. The workshop quieted. One evening, a boy wandered in, holding a shattered music box. "Can you fix it?" the boy asked. Elias smiled. He reached for his pliers, then paused. His hand went to his breast pocket.
A young woman came to him once. Her hands shook. "My voice," she said. "It comes out wrong. Apologizing for existing." Elias hesitated, then offered the tool. She pressed it to her sternum. Her eyes widened. "Oh," she whispered. "My I is a door with no handle from the inside." She left less broken, though not fixed. The tool didn't fix. It only showed the lock.
He found it years ago in the ruin of his grandfather’s study, after the old man’s slow forgetting had turned to silence. The study smelled of dust and terminated sentences. Among the blueprints and failed perpetual-motion sketches, the obsidian piece lay in a felt-lined box. No instructions. Just a single word etched on its face: I .
That was the true tool. Not the obsidian. Not the revealed identity. But the act of looking.
