Ra's al Ghul's knife is a magical artifact passed down by the leader of the League of Shadows to his successor. This embalming knife has the power to kill people who have been revived by the Lazarus Pit, instantly turning them to their true age.


The knife was used in ancient Mesopotamia to embalm King Balahsi in the first century.[1]

In the 21st century, it was used by Bruce Wayne to kill Ra's al Ghul, instantly mummifying him after he was tempted by Ra's al Ghul.[2]
