Trivia

 * The importance of the knowing name on the dagger is a play on the original Rumpelstiltskin fairytale, when he made a deal with the miller's daughter to discover his name.
 * The design is based on ritualistic Indonesian knives.
 * Cora refers to the dagger as a "kris dagger".
 * A kris is a prized Indonesian weapon known for its distinctive, wavy blade. They are considered to be spiritual objects.
 * If the Dark One is killed without the use of the dagger, he or she will expel the powers of the Dark One into the air after death without anyone else being next in line to inherit it, therefore ending the curse.
 * Goof: Throughout the series, the written letters of the Dark One keeps switching from one side of the blade to the other. Sometimes, the letters are right side up when the dagger is held in the right hand and facing the wielder with the first letter at the tip of the blade. At other times, the writing is right side up when the dagger is facing the wielder and held in the left hand with the first letter next to the hilt.
