English: The short sword barung is commonly used by the Tausug Moros of Sulu archipelago in the Philippines.
The pattern in the blade is what is called the piled structure: "[s]uch piled structures most likely naturally evolved from the need of smiths to join together multiple pieces of steel to form a larger fabrication such as a blade. The piled structure also has the potential to bring significant advantages in durability and localization of desired characteristics (hardness at the edge and fracture resistance at the back and center)."
