Morgul-knife in the New Line film
Knife of the Nazgul. The Morgul-knife was usually wielded by the Witch-King of Angmar. On October 6, 3018, it was used to stab Frodo Baggins, keeper of the Ring of Power, on Weathertop. The Morgul-knife's sharp blade broke apart in Frodo's shoulder. The poison almost went to his heart. If it had reached it, he would have become one of the Nazgul. The blade fell apart in sunlight. Though, on October 23, Elrond pulled the blade out of Frodo's shoulder and he was in a sense cured, he still felt pain in his wounded shoulder. The blade was melted after it was removed. It is not known if the pain still troubled Frodo after he departed from Middle-Earth in 3021.
