Not just bronze, pretty much anything will work.
During the Middle Ages, most men and women wore a small knife in a sheath as part of their daily dress and used it as an all-purpose eating utensil and tool. It’s use as a weapon has usually been secondary. It is not extraordinary that this was also the case in the bronze age. Also wealthier individuals generally had nicer daggers. Meteorite knifes or daggers were, and are, the most valuable, unique and have properties that are close to the best modern metal, almost magic in the old world. Knifes of this type have been found in the tombs of Pharaohs.

a dagger entombed alongside the mummy of Egyptian pharaoh Tutankhamun was made with iron that came from a meteorite, researchers say.
The weapon was one of a pair of daggers discovered by British archaeologist Howard Carter in 1925 within the burial wrappings of the teenaged king.
The origin of its unrusted iron blade has baffled scientists because such metalwork was rare in ancient Egypt.
Tutankhamun was mummified more than 3,300 years ago.
“Meteoritic iron is clearly indicated by the presence of a high percentage of nickel,” the study’s main author, Daniela Comelli, said.
