The Maduvu, also known as a maru or madu, is a weapon from India. It is one of the many weapons used in the Tamil martial art Silambam. More commonly known as a madu, it is also referred to as a maan kombu after the deer horns from which it is traditionally made, specifically those of the Indian blackbuck (Antilope cervicapra). A madu is treated like a double-bladed dagger. It typically consists of two blackbuck horns pointing in opposite directions connected by two crossbars which also act as a handle. Silambam experts use this weapon to confront opponents in various ways, both defensive and offensive.
