Question: who made zeus poseidon and hades weapons?
Answer: The cyclopes were divine craftsmen in general, serving as the primary builders and smiths of Olympus, assistants to Hephaestus. They didn't only make the weapons of Zeus, Poseidon, and Hades (in fact the Helm of Darkness they made for Hades is far more than a mere weapon), but also of Artemis and Apollo.
