In 1925, Howard Carter, who discovered King Tut's tomb, described the blade placed on the boy king's right thigh in burial as "a highly ornamented gold dagger with crystal knob." Recently, researchers from Milan Polytechnic, Pisa University, and the Egyptian Museum in Cairo used a X-ray fluorescence spectrometry to determine that King Tut's weapon is a space dagger. The blade's iron contains a significant amount of nickel, as well as unusually high traces of cobalt, confirming its meteoric origins. Seeker further explains the possible source of the blade:

"We took into consideration all meteorites found within an area of 2,000 km in radius centered in the Red Sea, and we ended up with 20 iron meteorites," Comelli said. "Only one, named Kharga, turned out to have nickel and cobalt contents which are possibly consistent with the composition of the blade," she added.

The meteorite fragment was found in 2000 on a limestone plateau at Mersa Matruh, a seaport some 150 miles west of Alexandria.
