The Whetstone of Tudwal Tudglyd
The Whetstone of Tudwal Tudglyd is one of the Thirteen Treasures of Britain. It would magically enhance the sword of a brave man should he sharpen it with this whetstone, enabling the sword to draw the very life out of any man wounded by the weapon. It would not however have any effect on sword that belonged to a coward.
