Are there any weapons abroad that have been confirmed to have been preserved for thousands of years? Like Gou Jian's sword, Wu Wang's sword and Fu Cha's spear?

Tutankhamun's golden dagger, about 1400 BC, is one of the oldest iron weapons in the world. It was once considered as a gift from the Hittites to Pharaoh, but recently it was found that its blade was made of meteorites, and its composition was consistent with that found in Egypt. The scabbard is made of gold, and the hilt is decorated with crystal and gold.

Philip II of Macedonia's helmet with golden armor and ivory iron sword were unearthed at the archaeological site of Vergina. Serious corrosion.

Sword of Tiberius, A.D. 1 century. Unearthed in Mainz, Germany.

It's not a weapon, but armor is ok, right?

The helmet of the marathon led by Athenian general Mi Tailhade was unearthed in the ruins of Olympia in 490 BC and kept in the Archaeological Museum of Olympia. After winning the marathon, all the Greeks offered sacrifices to the gods. Mityad presented his helmet to the temple in Olympia, and his name was engraved on it. As a trophy, the bronze helmet (lower right) is engraved with "Dedicated to Zeus, which the Athenians won from Medea (Persia)".

The most important thing to judge the authenticity of an unearthed cultural relic is not whether it is recorded in ancient documents, but whether its excavation process is clear and traceable, which is closely related to other cultural relics. But the time, place, age, owner and excavation record of this dagger are not clear.

Tutankhamun has two daggers in his coffin. In addition to this iron dagger on his leg, the other one is attached to the belt of Tutankhamun's mummy. Made of pure gold, it cannot be used as a practical weapon. It's just a ritual. The two daggers are very similar in shape and decoration style except for their different materials.
