Trishul (or Lord Shiva's Trident) is a type of Indian trident but also found in Southeast Asia. It is commonly used as a Hindu-Buddhist religious symbol. The word means "three spear" in Sanskrit and Pali.
In India and Thailand, the term often refers to a short-handled weapon which may be mounted on a danda or staff. But unlike the Okinawan sai, the trishula is bladed.
