Wasn't Silver Dagger supposed to have had associations with vampires ?
"In some countries, it was also believed that not unlike a werewolf, a vampire could be killed with a silver dagger, spear, knife and such."

Don't sing love songs; you'll wake my mother
She's sleeping here, right by my side
And in her right hand, a silver dagger
She says that I can't be your bride.

My daddy is a handsome devil
He's got a chain five miles long
And on every link a heart does dangle
Of another maid he's loved and wronged.
