The national emblem of Oman (Arabic: شعار سلطنة عمان) is Khanjar Bo Sayfain, an insignia consisting of a khanjar inside its sheath that is superimposed upon two crossed swords. Adopted in the 18th century as the badge of the Omani royal family, it subsequently became the national emblem of the Sultanate of Oman. The emblem is featured at the canton on the Flag of Oman.
