This rubber stunt sword was used by one of the Mummy's priest. The sword is constructed with a steel core and a rubber extertior to look like bronze. During the flashback that Evie has from her former life as Nefertiti, you see these guards by the bracelet of Anubis. It switches from live actors to the mummified versions of them. This looks to be aged as though its old so it was probably used in a fight scene from the modern time.
