Eighth Doctor's second sonic screwdriver

Later in his eighth incarnation, the Doctor carried a sonic screwdriver with a wooden handle. It had a metallic tip with six prongs that nested a clear diode at the end, which glowed blue when activated. (AUDIO: The Great War) Its handle doubled as a torch. (AUDIO: Sword of Orion) The Doctor claimed that he made this version of the sonic screwdriver to do more than open doors and blow up land mines. (AUDIO: X and the Daleks) He later made further modifications to the screwdriver. (AUDIO: Beachhead)

It was referred to as a pennywhistle by numerous World War I medics. (AUDIO: The Great War) The Doctor had it in his possession as early on as his travels with Charley Pollard, (AUDIO: The Light at the End) and was still using it in the early part of the Last Great Time War. (PROSE: Natural Regression) He had returned to using his original model by the end of his life. (TV: The Night of the Doctor)
