Third Doctor's Sonic Screwdriver (Sarah Jane Incidents)
A compact, cylindrical sonic screwdriver with a distinctive emitter tip showing heavy wear marks. Originally an emergency repair device for oxygen systems, it becomes a narrative symbol of partnership between the Doctor and Sarah Jane Smith across multiple events in The Sontaran Experiment and Nerva Station incidents. Scuffed metallic surface from frequent use, recognized immediately by Sarah's touch in abandoned ruins. Its restoration or absence drives key plot developments in environmental crises and survival confrontations.
