In a story I'm writing, I'm going to need iron to ward off magical creatures, faeries to be exact.
This iron should not be used in an alloy with other metals or coated with something like paint, tin, zinc or something like that. It should be relatively quick and easy to obtain from the enviroment. The iron would be used to ward off faeries since it would burn them on contact. Traditionally horseshoes and iron nails help against those creatures but try finding those lying around on the street.
What would be good sources to get things of just iron in today's world if you were dropped in an average English village? You have 15 minutes to get it in any way possible (including illegal activities, such as theft and vandalism) as your life is in danger.
