 According to the Chronicle of Greater Poland , the sword was kept in the treasury of the Wawel Cathedral . The ultimate fate of the original Szczerbiec is unknown . It may have been taken to Prague , together with other royal insignia , by King Wenceslaus II of Bohemia after his coronation as king of Poland in Gniezno in 1300 . What happened with these insignia thereafter remains a mystery . Although Boleslaus the Brave 's notched sword has not been preserved and even its very existence is doubtful , its legend had a great impact on Polish historical memory and the treatment of its successor , the modern Szczerbiec .
