He-Man Sword 1982 Vintage Masters of the Universe Weapon
He-Man came with a small plastic sword that could be joined into one with Skeletor’s purple sword. The swords were cast as one half of a Power Sword and when joined together, would be the key to Castle Grayskull according to the minicomics and lore. This same sword mold was used to create weapons for other figures such as Thunderpunch He-Man, Prince Adam, Dragon Blaster Skeletor, and Faker.
According the Grayskull Wiki, The main weapon of He-Man is his sword, “The Sword Of Power.” It is virtually indestructible, and can deflect rays magical or technological. The Sword Of Power can also shoot energy beams, and also absorb energy. Originally, He-Man’s primary weapon was an axe. The chest piece on his baldric (battle harness) is made of an Eternian mineral called coridite, that helps add to his physical strength.
