The sword currently known as Szczerbiec was forged and decorated in a style characteristic of the late 12th and 13th centuries, so it could not have belonged to any of the three great Boleslauses of the 11th and early 12th centuries. Additionally, it is a purely ceremonial sword which, unlike the original Szczerbiec, was never used in combat. It was originally used as a sword of justice ("gladius iustitiae"), or insignia of the sovereign's judicial power, by one of the many local dukes during Poland's Age of Fragmentation. A silver plate, now lost, on the sword's grip bore an inscription which indicated a duke by the name Boleslaus as its original owner. An inscription on the Radziwiłłs' replica of Szczerbiec, now also lost, could provide an additional hint as to the duke's identity: "Boleslaus, Duke of Poland, Masovia, and Łęczyca" – except that no duke of this name and titles ever existed. Historians have variously identified the duke in question as Boleslaus the Curly (), Boleslaus the Chaste (), Boleslaus I of Masovia () or Boleslaus the Pious of Greater Poland ().
