This is the 15th Century blade of the legendary Russian Ruler, Tsar Peter I (aka The Great). This is a ceremonial sword. Designed on the Straight Sword/Arming Sword combination design. It has an unusual cross hilt/handle pattern that is actually two-pieces (split). Further inlaid with gold filigree and precious jewels, Peter's sword is indeed a splendid weapon. Some debate about the swords authenticity is put into question. After the Russian Revolution of the early 20th Century, many articles of Imperial Russia disappeared or were destroyed. A sword purporting to be his is currently on display at The State Museum of St. Petersburg, St. Petersburg, Russia.
