 The Mughul invasion of Afghanistan and India brought these sabres to the subcontinent which developed into the Pulwar and Talwar respectively in the 16th century.While these Islamic blades often retained tunkou showing their Turko-mongol heritage, even by the 15th century the device had become a stylized decorative element.The Ottoman Yataghan, while not bearing a traditional curved sabre blade, did still bear the tunkou indicating their turko-mongol heritage.
