Why I no longer feel worthy to read Terry Pratchett's books...

With help from his friend Jake Keen—an expert on ancient metal-making techniques—the author dug up 81kg of ore and smelted it in the grounds of his house, using a makeshift kiln built from clay and hay and fuelled with damp sheep manure...Pratchett...also said he had thrown in "several pieces of meteorites—thunderbolt iron, you see—highly magical, you've got to chuck that stuff in whether you believe in it or not". After days of hammering the metal into bars, he took it to a blacksmith, whom he helped to shape it into a blade, which was finished with silverwork.
