Un hombre bueno va a la guerra
Despite the Doctor's claim not to give his screwdriver to anyone, he gives one to his own doppelgänger in "The Rebel Flesh", and gives his to Rory Williams in "The Girl Who Waited" after having either given or loaned one to him for use in "A Good Man Goes to War" and loaning him one in "The Big Bang". He also gives one to River Song in "The Husbands of River Song" which is then used by the Tenth Doctor to save her life in "Forest of the Dead".
