Satan's Tooth is forged of Lucifer's fang, which was knocked out when God cast him from Heaven. The dagger has a long and bloody history, passing from one serial killer to another, until one of those serial killers made the mistake of abducting Sandra Lords. And so Hellina found the dagger, and it finally had a wielder worthy of its evil legacy. The dagger can be controlled telekinetically, and appears in her hand at will.
