Sod a monthly direct debit: from now on try paying your rent in the form of crockery. OK, your landlord might not like it, but it works a treat for the City of London, which pays annual rent to the crown for several plots of land in the form of two knives – one sharp, one blunt. The payment also includes six horse shoes and 61 nails, all of which are presented in a ceremony called the ‘Rendering of the Quit Rents’ at the Royal Courts of Justice.
