Szczerbiec

Szczerbiec is the coronation sword that was used in crowning ceremonies of most kings of Poland from 1320 to 1764. It is currently on display in the treasure vault of the Royal Wawel Castle in Kraków as the only preserved piece of medieval Polish Crown Jewels. The sword is characterized by a hilt decorated with magical formulas, Christian symbols and floral patterns, as well as a narrow slit in the blade which holds a small shield with the coat of arms of Poland. Its name, derived from the Polish word szczerba meaning a gap, notch or chip, is sometimes rendered into English as "the Notched Sword" or "the Jagged Sword", although its blade has straight and smooth edges.
