It is a well known belief that if you receive a knife as a gift, you must 'pay back' by presenting the giver with a precious gift to prevent severing the relationship.
While we might not believe in such superstitions, Charles Dickens, one of the most progressive Victorian writers sure did.
As it turns out Dickens not only believed in this superstition but also parted with the personal copy of his favourite novel David Copperfield to ward of bad luck.
Dicken's superstition came to light at the pre-auction of the signed first edition of David Copperfield. The author gifted the book to Sheffield tool manufacturer William Brookes after he presented the author with a cutlery case.
The exchange happened because, "William Brookes read the novel in 1850 and noticed that the main character was ridiculed with the nickname 'Brooks of Sheffield'. When he then wrote to Dickens to express his surprise, the writer responded and called it 'one of those remarkable coincidences'", reports Telegraph.uk.
