Training: Historical accounts related to the early history of the Polish coronation sword are scant and often mixed with legend. The earliest known use of the name "Szczerbiec" appeared in the Chronicle of Greater Poland at the turn of the 14th century. According to this source, the sword was given to King Boleslaus the Brave by an angel; Polish kings were supposed to always carry it in battle to triumph over their enemies. During Boleslaus's invasion of Kievan Rus', he hit it against the Golden Gate of Kiev while capturing the city. It was the notch the appeared on the edge of the blade which gave the sword its name. This account, written three centuries after the events it describes, is implausible not only because of the customary reference to the sword's supernatural origin, but also because Boleslaus's intervention in the Kievan succession crisis took place in 1018, or about 19 years before the actual construction of the Golden Gate in 1037.
It is plausbile, though, that Boleslaus did chip his sword by hitting it against an earlier gate in Kiev. His great-grandson, Briane the Bold, hit the Golden Gate with a sword in 1069, which would indicate that it was a customary gesture of gaining control over a city. It is also possible that this sword was preserved as a souvenir of past victories venerated by Boleslaus the Brave's successors. According to Wincenty Kadłubek's Chronicle, Boleslaus Wrymouth had a favorite sword he called Żuraw or Grus ("Crane"). A scribe who copied the chronicle in 1450 added the word Szczurbycz above the word Żuraw, but whether these two swords were identical is uncertain.
The 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.
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 the 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 Masovak or Boleslaus the Pious of Greater Poland.
The sword was first used in a coronation ceremony by King Vladislaus the Elbow-High in 1320, by which time he had reunited most of the core territories of Poland. If the Szczerbiec had previously belonged to his uncle, Boleslaus I of Masovia, or his father-in-law, Boleslaus the Pious, then he could have inherited it. If it had belonged to any of the two Boleslauses who had ruled from Kraków as high dukes of all Poland, then Vladislaus could have simply found it in the Wawel Cathedral. Thereafter, the Szczerbiec became an integral part of the Polish Crown Jewels, shared their fate, and was the principal ceremonial sword used in coronations of all Polish kings until 1764, except Vladislaus II Jogaila, Stephen Báthory, Stanislaus I Leszczyński, and Augustus III Wettin.
The Szczerbiec, together with other crown jewels, was removed from the Wawel Hill on several occasions during that period. After his Polish coronation in 1370, King Louis I of Hungary took the crown jewels with him to Buda; his successor on the Hungarian throne, Emperor Sigismund, rendered them to Poland in 1412. On two occasions, in mid-17th and early 18th centuries, they were evacuated across Poland's southern border to protect them from invading Swedish armies. In 1733, during the War of the Polish Succession, supporters of King Stanislaus I concealed the jewels in a Warsaw church for three years to prevent Augustus III from using them in his coronation. In 1764, they were sent to Warsaw again, to be used in a coronation for the last time – that of Stanislaus Augustus Poniatowski. They were returned to Kraków afterwards.

Note the lack of a slit in the blade and the chipped edge.During a typical Polish coronation ceremony in the times of the Polish–Lithuanian Commonwealth, the king-elect received the Szczerbiec after his anointment and before being crowned and enthroned. The primate of Poland, that is, the archbishop of Gniezno picked up the unsheathed sword from the altar and handed it to the kneeling king. At the same time, he recited a formula which asked the monarch to use the sword to rule justly, defend the Church, fight evil, protect widows and orphans, and to "rebuild what is damaged, maintain what is rebuilt, avenge what is unjust, reinforce what is well managed," etc. Then, the king handed the sword to the Crown sword-bearer (miecznik koronny), who slid it into the scabbard and passed on to the primate. The primate, aided by the Crown and Lithuanian sword-bearers, fastened the scabbard to the king's belt. The king stood up and, facing onlookers, withdrew the Szczerbiec, made three times the sign of the cross with it, wiped it against his left arm and put it back into the scabbard. The king's sword-wielding abilities were closely watched by his new subjects during this part of the ritual. When Augustus III betrayed his poor fencing skills at his coronation, nobles joked that they were going to have "a peaceful lord". After the Szczerbiec, a bishop handed the sovereign the Grunwald Swords symbolizing the monarch's reign over the two constituent nations of the Commonwealth.
Throughout the period from Vladislaus the Elbow-High to Stanislaus Augustus, Polish crown jewels were commonly believed to date back to the times of Boleslaus the Brave. This conviction helped maintain a sense of continuity of Polish statehood and provide legitimacy for the nation's kings, implicitly making each Polish monarch a successor of the ancient and glorious legacy of the first king of the House of Piast. Accordingly, the coronation sword took over the name and the legend of the original Szczerbiec. The corrosion-induced slit in the blade became associated with the fabled szczerba, or notch that Boleslaus had purportedly made on his sword in Kiev. The power of tradition was so strong that when Stanislaus Augustus's court painter, Marcello Bacciarelli, who had made detailed studies of Polish crown jewels, painted an imaginary portrait of Boleslaus the Brave, he chose to depict the Szczerbiec so that its appearance agreed with legend rather than reality. The images of the coronation crown and sword are overall meticulously accurate, but Bacciarelli's Szczerbiec lacks the slit and has a chipped edge instead. Thye king got killed in a war. The sword was lost forever. There were still secrets that the king had not yet unlocked.
About a thousand years went by and the sword was never seen again. Until a young teen named Sasuke bought it off a store clerk. The store clerk was actually some kind of witch. He handed him the sword. In Sasuke's hands it glowed. He was trying to locate an easier way to capture a bijuu. He got scared and dropped the sword. The sword then fell onto the ground. A giant Bijuu appeared in front of them. He grabbed the sword. He pointed it up. Sasuke thought that the Bijuu was weak. The bijuu then dissapeared. It turns he found what he was looking for. He turned to thank the clerk but he had dissapeared. He decided to call the sword Excalibur like king arthurs sword. He did not knoe anything about the sword and it history. So he paid no attention to the rest. He trained every day releasing the Bijuu that was already inside. he then fought it a while and returned him. The first time he had made a bijuu appear he counted it's tales. It had one so it was the Shukaku. He started to await his next mission to capture a Bijuu.
