Dr. Schliemann has just deposited in the British Museum a dagger believed to be made of meteoric steel and exhumed by him in the royal palace of Troy. This is the first iron discovered by him in his excavations, either in the Troad or the Peloponesus, and is of the very greatest archaeological interest.
All I know about Archaeology, I learned from reading Elizabeth Peters. Emerson would not like Herr Schliemann, I suspect.
If you do a search on “dagger meteoric steel” you’ll get tons of references to various items that indicate you’ll get some sort of attack bonus. In other words, the D&D/RPG crowd think the meteoric steel is somehow better than ordinary steel made of terrestrial iron. I would guess that the meteoric steel in ancient times was better, simply because it got hotter by coming through the atmosphere than a wood/coal fire could generate, and cooled slowly to temper it. I’m not going to refer you to phase diagrams of hardened steel production — it will cause me to have nasty flashbacks.
