Man in Black's ancient dagger
This pugio, a Roman military dagger, was used throughout Season Six. Originally used by the Man in Black to kill Mother, it was later given to Richard Alpert by the Man in Black to kill Jacob. Unable to do so, Richard held possession of the dagger since 1867 until it is next seen in the possession of Dogen. Dogen gives the dagger to Sayid instructing him to use it to kill the Man in Black. Includes one 15 in. metal dagger with sheath and a retractable version of the same dagger.
