One of the characteristics of Filipino martial arts is the use of weapons from the very beginning of training and Modern Arnis is no exception. The primary weapon is the rattan stick, called a cane or baston (baton), which varies in size, but is usually about 28 inches (71 cm) in length. Both single and double stick techniques are taught, with an emphasis on the former; unarmed defenses against the stick and against bladed weapons (which the stick is sometimes taken to represent) are a part of the curriculum. Training covers empty-hand self-defense (striking, locking, throwing, etc.) as well as the trademark single and double stick techniques of the Filipino martial arts. Other aspects of the art include espada y daga (sword and dagger fighting), sinawali (double stick weaving patterns), and tapi-tapi (locking drills with the stick).
