Stone Knife

The Stone Knife was the knife that Jadis the White Witch used to kill Aslan on the Stone Table during the Narnian Revolution as well as at the Battle of Beruna.

History
Susan and Lucy, who witnessed the execution of Aslan, noticed it had a 'strange and evil shape'.

The Knife appeared again on Ramandu's Island during Lucy, Edmund, and Eustace's travels about the Dawn Treader. It was seen lying on a long ceremonial table where three sleeping men were sitting, appearing as though they had been there for years. Ramandu's daughter explained to Edmund, Lucy, and Caspian that it was brought there after Aslan's resurrection, to be kept in honour for as long as the world existed. The three men, sailors, came to the island and during a quarrel between them, one of the men picked up the Knife, meaning to stab his comrades. As it was not right for him to touch it, when his fingers closed upon the hilt, the three fell into an enchanted sleep. The only way to save them from this enchantment was to go to the world's end, leave at least one of their companions, and come back without that companion forever. Though there was much dispute as to who would be left behind, Reepicheep was the one to stay.
