Re. the sizes and differnent kinds of Filipino martial arts sticks: Stick length is often determined by the kind of sword for which the stick is a surrogate. I practice San Miguel Eskrima, for example, and our stick length of about 32-33 inches reflects the fact that a pinute would be used in place of the stick if you were using a sword. A friend of mine practices both Pekiti Tirsia Kali and Serrada Escrima; a stick length of about 26-27 inches reflects the fact that a ginunting is a representative sword for Pekiti Tirsia Kali; a stick length of about 18 inches reflects the fact that a bolo is a representative weapon for Serrada Escrima. It's interesting to note that it is generally the length of the weapon that dictates the footwork, angling, distancing, and body mechanics of the art (and thus makes various Filipino martial arts look different from one another). With respect to the terms "kali," "arnis," and "eskrima": There are dozens, if not hundreds, of regional terms used for armed combat in the Philippines that reflect the enormous cultural diversity of the nation. These terms are often in languages or dialects that are only spoken in one area of the country and nowhere else. The most common terms that come from the Spanish are "arnis" and "eskrima," and although there is some etymological evidence that the term "kali" does in fact connote the use of weapons, the actual use of the term in the Philippines is rare to the point of being almost nonexistent. However, when the Filipino martial arts were first promoted in the the United States, the term "kali" was used to draw attention to the ancient aspects of Filipino martial arts, which gave rise to an interpretation that "kali" represented the ancient arts, "eskrima" the arts that arose during the Spanish occupation, and "arnis" the arts of the modern era. Other interpretations of the terms give them geographical significance: "kali" represents the arts of the southern Philippines, "eskrima" represents the arts of the centeral Philippines, and "arnis" represents the arts of the northern Philippines. The bottom line is however that "arnis" is the most common general term used in all parts of the country, and that regional terms are more likely to be recognized in those areas of the country. The terms "kali," "arnis," and "eskrima" are used interchangably here in the United States and in Europe, and I suspect that they will become a part of the lexicon in much the same way as "coke" or "xerox" have. If you go to the Philippines, however, the terms "arnis" and "eskrima" are recognized as generic terms for the Filipino martial arts. Best, Steve Lamade Instructor San Miguel Eskrima Association
