Yes. All weapons were fight-worthy - no dull blades or flimsy props. The sticks were kamagong or bahi.
Also, you said that they try to use live weapons whenever possible, does that mean that the katars and knives used in sparring were sharp?
We also did a multiple opponent drill, with one person standing in the centre of the circle, sort of a zombie town scenario, and the goal was to make it to the outside. Unsurprisingly, we all died like punks.
]While I don't think that you can really "win" against multiple opponents with any sort of consistency, I've found that I survive longer than I used to when my FMA class does multi-person sparring, and sometimes I can even successfully run away.
