I lived there for 4 years and had travelled there for the previous 20, usually once a year or more often to train, dive and be an ambassador for my country (official lie but 'barfining' is frowned upon in some forums). I trained the local Barangay Tanod or volunteer community police, these local guys were the ones most likely to attend as first responder at the cockpits, KTV bars and so on where fights would happen. I rode along with them many times in Bogo and Talisay and Calape, all places on Cebu, plus had some interaction to a lesser degree in Manila and Angeles City.
Most of the fights were fist fights and they were like any pub brawl anywhere. Wild swinging and leaning back when punching to avoid getting hit and then tearing shirts and grappling and falling to the ground. Unless one got the drop on the other and as he went down from the king hit (sucker punch) he was hammered into the dirt. Pretty one sided stuff.
Knives, bolos, machetes etc were next. Never saw a balisong/butterfly/fan knife although you can buy them in the sports department of the local Gaisano Dept Store along with brass knuckles and arnis sticks. Mostly they used either bolos used on the farm or around the garden or kitchen knives.
Quite a few used guns, mostly 'Paltik Pusil' the local Saturday Night Special. While the guns vary in quality the ammo is usually rubbish. I had a colleague I taught English with, an American who had lived there since he was a boy and spoke the language fluently, shot twice in the back at point blank range. His friend popped one round out with finger and thumb and the doctor took the other out with tweezers. Low powered reloads are common and many have bad casings and jam, which is why I bought a .22magnum revolver off my aunty-in-law the gun maker (I kid you not!). I felt it was more reliable and I could put all 8 rounds in the same hole from a foot away if need be.
The Tanod carried sticks but rarely used them. I taught them to close and grapple with the stick and use them for controlling offenders. See Hock's new DVD from Paladin (I think) for a look at that stuff. There is some footage of Remy Presas using a stick for take downs and locks on one of the threads and it also shows how useful the stick is at grappling range.
You can go to the Philippines and train but it would be prudent to identify who was going to milk you of your money first, before flying out. If you are in the UK, look up
http://www.rapidarnis.com/ Pat O'Malley from the Rapid Arnis school. If he can't help you he can point you towards someone who can. He also travels there regularly and takes groups with him. You only need to go to the Philippines to train for the 'street cred' and the adventure. You will get much better quality instruction at home (same in USA, Canada or Aust in my opinion).
