On occasions Wonder Woman has employed a magical sword of unknown (though presumably Amazon) origin. This sword has been used most specifically against those with the power of invulnerability as invulnerability generally does not work against magical items. It is generally represented as a short sword. In Wonder Woman (vol. 4) #15, Hephaestus modifies Diana's bracelets so that she can manifest two short swords from them during battle.
In one episode, a newspaper editor named Brown, desperate to discover Wonder Woman’s past, assigns a team of reporters to chase her down; she easily escapes them. Brown, gone half mad, is committed to a hospital. Wonder Woman disguises herself as a nurse and brings him a scroll. “This parchment seems to be the history of that girl you call ‘Wonder Woman’!” she tells him. “A strange, veiled woman left it with me.” Brown leaps out of bed and races back to the city desk, where he cries out, parchment in hand, “Stop the presses! I’ve got the history of Wonder Woman!” But Wonder Woman’s secret history isn’t written on parchment. Instead, it lies buried in boxes and cabinets and drawers, in thousands of documents, housed in libraries, archives and collections spread all over the United States, including the private papers of creator Marston—papers that, before I saw them, had never before been seen by anyone outside of Marston’s family.
